What do you not understand
Answer:
Step-by-step explanation:
Move all terms to one side
4x^2 + 4x + 5 = 0
Plug into quadratic formula
x = (-4 <u>+</u>
) / 2(4)
= (-4 <u>+</u>
)/8
At this point, there are no real answers. The roots to this equation are complex.
x = (-4 <u>+</u> 8i)/8
= (-1 <u>+</u> 2i)/2
4.7 because if you plug it in- (2,1) and (6,6) it is 4.7 units
Answer:
x=-27
Step-by-step explanation:
x/-9=3
x=3*-9=-27
