Factor the equation below.
f(x) = x2 + x - 20

f(x) = (x+5)(x-4)

Step-by-step explanation:

Key skills used in this problem: Quadratic equations, factoring

1) The equation x^2 + x - 20 is factorable (meaning it can be facttored easily)

2) We need to find factors of -20 that add up to 1. This is because our ac (a term times the c term) is -20 and our b term (the coefficient for +x) is 1.

3) The two factors would be 5 and -4.

4) So it would be (x + 5)(x - 4) when factored

Hope you understood and have a nice day!! :D

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.

do it yourself this is easy
