Step-by-step explanation:

for a cubic equation ax³+bx²+cx+d=0,

sum of the roots = -b/a

product of the roots = -d/a

sum of product of a pair of roots = c/a

using these above formulas, we can get those answers.

note: for an expression, roots are also called as zeroes because when expression is substituted with roots, it results in 0.
