Write the polynomial in factored form<br><br> x^3-2x^2-35x=
slamgirl [31]
Answer:

<span>x=6</span>, <span>x=−5</span> or <span>x=9</span>

Explanation:

<span><span>f<span>(x)</span></span>=<span>(x−6)</span><span>(x+5)</span><span>(x−9)</span></span>

If all of the linear factors are non-zero, then so is their product <span>f<span>(x)</span></span>.

If any of the linear factors is zero, then so is their product <span>f<span>(x)</span></span>.

So the zeros of <span>f<span>(x)</span></span> are precisely the values of x which make at least one of the linear factors 0, namely: 6, <span>−5</span> or 9.

-2(8m+8) = -16

-16m - 16 = -16

His first mistake lies in his distribution. When multiplying -2 * 8, he made it a positive 16, when he should have made it a negative 16.

-16m - 16 = -16

Add 16 to each side.

-16m = 0

Divide that by -16

m = 0
