Ineed to know how to do this problem i am completely stuck

This is FACTORISATION.

To solve this problem we have to find the common terms in this equation.

Firstly, between the 5x³ and 10x² the like terms are 5. But the question is, where did the 5 come from? Well in Factorisation, we have to find the HCF between two terms. Here is my

5x³+10x²-25x-50

5x²(1x+2)-25(x+2)-› HCF of 5 and 10 is 5, HCF of 25 and 50 is 25

(1x+2)(5x²-25)-› Add the numbers from the brackets and the numbers outside the brackets.

SO THE ANSWER IS (1x+2)(5x+25)

HOPE THIS HELPS ;)

(w – 2.5)(w + 2.5)

(–4v – 9)(–4v + 9)

step-by-step explanation:

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.
