If(x+9)is a factor of the polynomial 2x^2+2ax+5x+10find the value of a.

Answer»

ANSWER:

G(X)= x+9

=x+9=0

x=-9

p(x)= 2x²+2ax+5x+10

putting x=-9

2(-9)²+2a×(-9)+5×(-9)+10=0

=2×81+2a(-9)+5×(-9)+10=0

=162-18a-45+10=0

=-18a=-162+45-10

=-18a=-172+45

=-18a=-127

a=-127/-18

a=7.05

hope IT HELPS....!!!
