Question

check whether 7 + 3x is factor of 3 X square + 7 x​

Answer 1

Answer:

yes.

Step-by-step explanation:

given equation is 3x²+7x.

and if 7+3x is a factor then the remainder is 0.

let 7+3x=0

x=-7/3

p(x)=3x²+7x

p(-7/3)=3(49/9)+7(-7/3)

p(-7/3)=(49/3)-(49/3)

p(-7/3)=0

so. 7+3x is a factor of 3x²+7x.
