We can see that 2x - 8x + x = -5x
and -6y + 11y = 5y
and 9 - 14 = -5
so simplified, it is -5x + 5y - 5
Answer:
-17+7i
Step-by-step explanation:
Answer:
Step-by-step explanation:
1-x²=-(x²-1)=-(x-1)(x+1)
L.C.M.=(x+1)(x-1)³
F(x) = x^2 - 3x - 7
f(-3) = (-3)^ 2 - 3(-3) - 7
f(-3) = 9 + 9 - 7
f(-3) = 18 - 7
f(-3) = 11
