Answer:
4.4166666667 or 4.417
Step-by-step explanation:
7÷12-5=4.4166666667 or 4.417
Factor the equation out into (x-5)(x+3)
(x-5)=0
x=5
(x+3)=0
x=-3
x=5, -3
It would be half of the coefficient of x squared added to both sides:
So half of 8 ( the coefficient of 8x) is 4;
The number 4 squared is 16, so you would add that to both sides.
You do this so that you can easily factor the left side: x^2 + 8x + 16 = 4 + 16
(x + 4)(x+4) = 20
