ganeshie8 · Answer

(3x^2 + 4x - 3) subtracted from (x^3 - 2x + 3)?

ganeshie8 · Answer

since we want to subtract it, we put a minus sign

e.cociuba · Answer

Correct but u cant subtract things tht are not like terms right?

ganeshie8 · Answer

(x^3 - 2x + 3) - (3x^2 + 4x - 3)

ganeshie8 · Answer

you're right ! so we simplyify only like terms. and keep other terms as it is.

ganeshie8 · Answer

(x^3 - 2x + 3) - (3x^2 + 4x - 3)

first multiply the minus sign across

ganeshie8 · Answer

(x^3 - 2x + 3) - 3x^2 - 4x + 3
