(8x2-4x-8)(2x2+3x+2)

Sagot :

Answer: 12x squared + 2x + 96

Step-by-step explanation: We first simplify the parentheses. 8x2 = 16 - 4x - 8 = 16-8-4x = 8-4x. 2x2 = 4 +3x+2 = 4+2+3x = 6+3x. So, we are left with (16-4x)(6+3x).  We rearrange the problem so it looks like this: (-4x + 16)(3x + 6). -4x(3x+6)  + 16(3x+6). Now we just multiply. And, we get 12 x squared + 2x + 96
