Question

How do I do this? x(3x -5) +7(x^2 - 2x+9)

Answer 1

multiply out using distributive property, then combine like terms

Answer 2

\[3x^2-5x+7x^2-14x+63\] is your first step

Answer 3

thank you but I dont know how to reorganise it the negative terms so I can add like terms

Answer 4

so you would make it \[3x^{2}-7x ^{2}-5x-14x +63 \]
and then solve it using the like terms
