Question

Solve by factoring and using the principle of zero products.

x2 - x = 12

Answer 1

x^2 - x - 12= 0 find the factors of -12 that add to -1

(x -4)(x+3)=0

Answer 2

Factor by grouping.

x3 + 5x2 - 2x - 10

Answer 3

x(x^2 -2) + 5(x^2 - 2) = (x+5)(x^2 -2) this is grouping in pairs

Answer 4

thanx
Factor by grouping.

x3 - 4x2 - 8x + 32

Answer 5

x(x -8) -4(x^2 -8) = (x -4)(x^2 - 8)

Answer 6

easy... find 2 factors of -48 that add to 2.... good luck
