Question

Find the number of terms in the polynomial 4x(2x+9-3x^2). Also, write the coefficient of x^2.

Answer 1

Ouestion :- Write the coefficient of x 2 of the

following: (2x−5)(2x2−3x+1)

Answer :- The given polynomial can be written

as: (2x−5)(2x2−3x+1)=4x3−6x 2+2x−10x2+15x−5=4x

3 −16x 2+17x−5

So, the coefficient of x 2 in the given polynomial is −16.
