Question

value of U.
Divide the first polynomial by the second polynomial and find the
(4) For the polynomial mx- - 2x + 3 if p(- 1) = 7 then find m.​

Answer 1

Given

p ( x ) = mx - 2x + 3

So

p ( - 1) = m(-1) - 2(-1) + 3 = -m + 2 + 3 = 5 - m

But

p(- 1) = 7

So

$5 - m = 7$

$- m = 2$

$m = - 2$
