If you would like to solve the quadratic function by completing the square, you can do this using the following steps:
- 32 = 2(x^2 + 10x)
- 32 + 50 = 2(x^2 + 10x + 25)
18 = 2(x + 5)^2
9 = (x + 5)^2
<span>± sqrt(9) = x + 5
</span><span>± 3 = x + 5
</span>x = - 2 or x = - 8
Move the -3 to the other side which makes it 41 + 3 = 44
So now the equation looks like 4x=44
Now divide 44 by 4, equals 11
x=11
Answer:
Solving proportions is simply a matter of stating the ratios as fractions, setting the two fractions equal to each other, cross-multiplying, and solving the resulting equation.

Answer:
10 +8i
Step-by-step explanation:
You add these the same way you would if they were considered to be polynomials.
(7 +2i) +(3 +6i) = (7 +3) +(2 +6)i = 10 +8i
The quotient is 294 16/25
