Jay factored the 4 term polynomial : x^3 - 9x +2x^2 - 18 and decided that the complete factorization was : ( x + 2 ) (x^2-9 ). before turning in his paper, he checked his final factorization by multiplying out his factors and was sure that he had found the correct factors. when his teacher graded his paper, she marked his answer as incorrect, but gave him one more chance to show the correct factorization.
a) what was jay's mistake?
b) show/describe each step in factoring the 4 term expression correctly and completely : x^3 - 9x +2x^2 - 18

Sherina wrote and solved the equation. x-56=230 x-56-56=230-56 x=174 what was sherina’s error? sherina’s work is correct. sherina only needed to subtract 56 from 230. sherina made a subtraction error when subtracting 56 from 230. sherina should have added 56 to both sides of the equation.
