5x + 14 = 95 - 4x 5x + 4x = 95 - 14 9x = 81 x = 81/9 x = 9
ANSWER: -4X2 -8X-4x (x+2)= (-4x * x) + (-4x*2)= -4X2 -8X
81 8x9 is 72
71 multiplied by 81 is 5,751.

If that's 16x2 + 72x + 81, that factors to (4x + 9)(4x + 9) or (4x + 9)2
what is the product of ( 4x-7) (4x+7)
5x + 14 = 95 - 4x 5x + 4x = 95 - 14 9x = 81 x = 81/9 x = 9
There is a formula for factoring the "difference of squares." In this case, the answer is (9 - 4x)(9 + 4x)
ANSWER: -4X2 -8X-4x (x+2)= (-4x * x) + (-4x*2)= -4X2 -8X
4x
8x + 8 = 4x 4x + 8 = 0 4x = -8 x = -2
81*4 = 324
81 x 24 = 1944
81 multiplied by 38 is 3,078.
81 3x3x3x3=81
