X^3 + 4x^2 + 5x +20 factor by grouping

Step-by-step explanation:

x³ + 4x² + 5x + 20

x² (x + 4) + 5 (x + 4)

(x² + 5) (x + 4)

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.
