Answer:
The answer would be the first one, combining 8 and -2
Step-by-step explanation:
This is because the 2 like terms are 8x^2 and -2x^2. You can get this by looking in the problem. There are 2 terms with x^2 which means we have to combine them. One of them is 8x^2 (the 1st one) and the other is -2x^2 (since it says 7-2x^2)
If you combine these you will get 6x^2 [8+(-2)=6]
A=4 because √a=-2 the you square each side to make it a=4.
