Me factorise (2x-1)^2-(3x+6)^2 . explain your answer too, you xx

- 5(x + 1)(x + 7)

Step-by-step explanation:

Expand the given factors in the expression

= 4x² - 4x + 1 - (9x² + 36x + 36 )

= 4x² - 4x + 1 - 9x² - 36x - 36 ( collect like terms )

= - 5x² - 40x - 35 ( factor out - 5 from each term )

= - 5(x² + 8x + 7) ( factor the quadratic )

= - 5(x + 1)(x + 7)

y=mx+b

step-by-step explanation:

m slope, b y-intercept

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.
