Im sorry but you did it wrong. Remember your order of operations. First do whats in parenthasis, so nothing then exponents. catch me first off is you will get this when you substitute in. 3(-2)^2-5*-2. so you square your -2 which gives you -4 so now you got 3*-4-5*-2. so now we do our multiplication and divsion. -12+10 and we get -2
3x^2 - 5x
when x=-2 we get
3(-2)^2 - 5(-2)
= 3(4) + 10
= 12 + 10
