Answer:
D
Step-by-step explanation:
The black triangle is on -1, 1.
The red triangle is on 1, -1. The axles have flipped.
(10х — 4х2) - (7х + ?) = 3х – 6х2
10x - 7x = 3x which is given,
Now you have -4x^2 - ? needs to equal -6x^2
write it as an equation:
-4x^2 - ? = -6x^2
To solve for ? add 4x^2 to each side:
-? = -2x^2
Multiply each side by -1:
? = 2x^2
