To find the solution to the equation using factoring, we need to first write it in standard form. Which of the following choices is equivalent to the equation:
(x - 3)(x + 5) = 10

x^2 + 2x - 5=0
x^2 + 8.2 – 25 = 0
x^2 + 2x – 25 = 0
x^2 + 2x + 5 = 0

the answer is x^2+2x-25

Step-by-step explanation:

Use distributive property

Multiply the two x’s by each other

Multiply the first x by +5

Multiply the -3 by x

Multiply the -3 by +5

You have x^2+5x-3x-15=10

Move the 10 to the left side and simplify

x^2+2x-25

11 feet 6 inches and 8 feet 6 inches

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse
