1 Answer. **x2**+**4** cannot be **factored** using real number coefficient. Depending on your class, that may be enough of an answer. If you really need to **factor** completely and are allowed to use complex numbers, you **can**.

What is x squared factored?

The expression (**x2**–**2**) is a classic example of a difference of two squares. In **factoring** a difference of two squares, any expression in the form of (a**2**-b**2**) is reduced to (a-b)(a+b). The key to this **factoring** process and ultimate solution for the expression (**x2**–**2**) lies in the square roots of its terms.

**What is quadratic equation in math?** A **quadratic equation** is an **equation** of the second degree, meaning it contains at least one term that is squared. The standard form is ax² + bx + c = 0 with a, b, and c being constants, or numerical coefficients, and x is an unknown variable. **Can x squared plus 9 be factored?**

You cannot simplify **x**^**2** + **9** with real numbers but you **can** use the imaginary number system. But if you are looking to evaluate the entire expression you should have (**x**+3)(**x**^**2**+**9**)=0 and if **x**=-3 then you have (0)(a quantity) or the zero product property. This is as far as this **can** be **factored** Ashleigh.

**How do you Factorise completely?** **Factoring completely is a three step process:**

### How do you factor 4x 2 1?

Step by step solution : Step 1 : Equation at the end of step 1 : 22×2 – 1. Step 2 : Trying to factor as a Difference of Squares : 2.1 Factoring: 4×2-1. Check : 4 is the square of 2. Check : 1 is the square of 1. Check : x2 is the square of x1 Factorization is : (2x + 1) • (2x – 1) ### Does x plus x equal 2x?

Therefore if we think of x instead of apples, it is clear that the answer x plus x is 2x. ### Does 2x equal x squared?

Because multiplication is commutative, x2 and 2x would be the same thing. But x2 means x times x. Hi Brithany. 2x and x2 are the same. ### What does X equal in the equation?

b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane. x is the value of the x-coordinate. An equation such as y=x+7 is linear and there are an infinite number of ordered pairs of x and y that satisfy the equation. ### Is X squared plus x squared 2x squared?

Answer and Explanation: x-squared plus x-squared is equal to 2 times x squared. Calculating x-squared plus x-squared is a matter of combining like terms. ### How do you solve for x in a quadratic equation?

Often, the simplest way to solve “ax2 + bx + c = 0” for the value of x is to factor the quadratic, set each factor equal to zero, and then solve each factor. But sometimes the quadratic is too messy, or it doesn’t factor at all, or you just don’t feel like factoring. ### What are the 4 ways to solve a quadratic equation?

The four methods of solving a quadratic equation are factoring, using the square roots, completing the square and the quadratic formula.
