A.5,8 and 4,5
B.5,8 and 4,3
D. 4,5 and 4,3

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.

The answer is (a) 12-2(-1)(6)2(6)=12

X=-4 the correct answer
