Answer 7

(2x-3)(x^2-10x+30)
(Expand the expression)

2x*x^2-2x*10x+2x*30-3x^2-3(-10)x-3*30
(Determine the sign)

2x*x^2-2x*10x+2x*30-3x^2-3*10x-3*30
(Multiply)

2x^3-20x^2+60x-3x^2+30x-3*30
(Calculate)

2x^3-20x^2+60x-3x^2+30x-90
(Combine like terms)

2x^3-23x^2+90x-90
(This is the answer)

Answer 16

idea is to write co-efficients of x^3,x^2,x and constant term
\[2x^3+(-20-3)x^2+(30+60)x+(-90)=2x^3-23x^2+60x-90\]
