Question

Find m so that ( - 4)m + 1 × ( -
4)2 = - 64. ​

Answer 1

Answer:

4x

2

−6x+m is divisible by x−3

So,

If 4x

2

−6x+m is divisible by x−3 then

m+18=0

m=−18

So, −18 is an exact divisor of 36.

Answer 2

Answer:

heya mate

$( - 4)m + 1 \times ( - 4)2 = - 64 \\ \\ = > - 4m + 1 \times ( - 8) = - 64 \\ \\ = > - 4m - 8 = - 64 \\ \\ = > - 4m = - 64 + 8 \\ \\ = > - 4m = -56 \\ \\ = > 4m = 56 \: ( - \: - \: cancelled) \\ \\ = > m = \frac{56}{4} \\ \\ = > m = 14$

hope it helps u ✅
