Rewrite (x – 3) (x + 5) + (x – 3) (2x – 1) as the product of two binomials.

(x - 3)(x + 5) + (x - 3)(2x - 1)

We can factor out (x - 3) since both terms have that in common. Then we simply add together x + 5 and 2x - 1

(x - 3)(3x + 4) is the final answer.

The answer is approximately ±6.32

Step-by-step explanation:

Given the quadratic equation 40-x² = 0, to get the solution to the quadratic equation, we must find all the values of x that satisfies the equation.

From the equation 40-x²= 0

Step1: Take -x² to the other side of the equation to have;

40= 0+x²

40= x²

Step 2: Take the square root of both sides to have;

√40 = √x²

x = ±√40

x = ±6.32

The values of x are approximately 6.32 and -6.32
