Question

complete the problems below. involving trinomials and difference of squares.Factor.1. ) x^2 + 18x + 812.) x^2 + 7x + 123.) 9x^2 + 6x – 84.) 16x^2 – 15.) 25x^2 – 49

Answer 1

For this case we have this:

Part 1

x²+18x+81= (x+9)(x+9)

Part 2

x²+7x+12= (x+4)(x+3)

Part 3

9x²+6x-8=(3x+4)(3x-2)

Part 4

16x²-1= (4x-1)(4x+1)

Part 5

25x²-49 =(5x-7)(5x+7)
