Question

Q2 What is the value of the coefficient of the x^2 term when the expression (3x^2−4+2.5x) is multiplied by (−3x−0.25)?

Answer 1

Multiply and collect x^2 terms:

(3x^2)(−0.25) = −0.75x^2 and (2.5x)(−3x) = −7.5x^2.

Sum: −0.75 − 7.5 = −8.25 = −33/4.

So the coefficient is −33/4 (or −8.25).
