Question

factor each polynomial
2x² -8x=2(2x-4) and x²+7x+12 =(x+3)*x+4)

pls show step by step solution

Answer 1

Answer:

Let f(x)=2x  

3

−kx  

2

+7x−1.

Now according to the remainder theorem, when f(x) is divided by x−1 then the remainder is f(1).

Now, f(1)=2−k+7−1=8−k.

According to the problem,

8−k=3

or, k=5.
