Question

2xpower3-kx+7x-1 divide by x-1

plz slove this

Answer 1

Your question is incomplete,

Complete question : find the value of k.

××××××××××××

Given that (x - 1) is the Factor,

Then, x - 1 = 0

x = 1

=============

Putting the value of x in given equation,

2x³ - kx² + 7x -1 = 0

2(1)³ - k(1)² +7(1) - 1 = 0

2 - k + 7 - 1 = 0

9 - 1 - k = 0

8 - k = 0

8 = k

I hope this will help you

Answer 2

Heya ✋

Let see your answer !!!!!

Your question needs correction.

$let \: p(x) = 2x ^{3} - kx + 7x - 1 \\ let \: g(x) = (x - 1) \\ = > x - 1 = 0 \\ = > x = 1$
$p(1) = 2 \times 1 ^{3} - k \times 1 + 7 \times \\ 1 - 1 \\ = > 0 = 2 \times 1 - k + 7 - 1 \\ = > 0 = 2 - k + 6 \\ = > 0 = 8 - k \\ = > k = 8$



Thanks :))))
