Factor by grouping. Group up the terms into pairs, factor each pair, then factor out the overall GCF.
x^3 + 2x^2 - 16x - 32
(x^3 + 2x^2) + (-16x-32) ... pair up terms
x^2(x + 2) + (-16x - 32) ... factor x^2 from the first group
x^2(x + 2) - 16(x + 2) ... factor -16 from the second group
(x^2 - 16)(x + 2) .... factor out (x+2)
(x - 4)(x + 4)(x + 2) .... Use the difference of squares to factor x^2-16
---------------------------
The original expression completely factors to (x - 4)(x + 4)(x + 2)
The three factors are x - 4 and x + 4 and x + 2
The answer is 25 because
5*5=25
Answer:
I am not sure, but i think it is A
Step-by-step explanation:
Answer:
<u><em>Answer is below</em></u>
Step-by-step explanation:
<u><em>10=3x-8</em></u>
<u><em>always remember to flip the equation</em></u>
<u><em>3x-8=10</em></u>
<u><em>Add 8 to both sides</em></u>
<u><em>3x-8(+8)=10(+8)</em></u>
<u><em>3x=18</em></u>
<u><em>Divide both sides by 3</em></u>
<u><em>3x/3=18/3</em></u>
<u><em>x=6</em></u>
