Question 146476: given the following polynomial:
p(x)= 5x^3-3x^2+2x+7x^2
determine p(3)
classify p(x) as monomial, binomial, trinomial or neither of these Thanks
Answer by aswathytony(47) (Show Source): You can put this solution on YOUR website!
p(x) = 5x^3 -3x^2+2x+7x^2
here there are two x^2 term, so combining
p(x) = 5x^3 +4x^2 +2x , since p(x) contains three terms , its a trinomial.
when we substitute x = 3 in p(X) , we get p(3)
p(3) = 5(3)^3 + 4(3)^2 + 2 (3)
= 5* 27 + 4 * 9 + 6
= 135 +36 +6
= 177.
