Question

For the polynomial mx^2-2x+3 if p (-1)=7 then find m.

Answer 1

p(x) = mx²-2x +3
p(-1) = m(-1)²-2(-1)+3
7 = m +2+3
m= 2

Answer 2

Answer:

The value of m is 2 if p(-1)=7

Step-by-step explanation:

Given polynomial $mx^2-2x+3$

we have to find the value of m if p(-1)=7

$p(x)=mx^2-2x+3$

$p(-1)=m(-1)^2-2(-1)+3$

$7=m+2+3$

$m=2$
