Question

x2+3x+p ÷ x-2 find the value of p

Answer 1

Answer:

-10

Step-by-step explanation:

f(x) = x² + 3x + p

f(2) = 2² + 3(2) + p = 0

=> p = - 10

Answer 2

Answer:

If x-2 is a factor then x-2=0

x=2 is a root of the quadratic equation

Substituting in x²+3x+p=0

=2²+3×2+p

=4+6+p

=10+p=0

P=-10
