4(11-x) = (x-3)^2
4(11-x) = (x-3)(x-3)
4(11-x) = x^2 - 6x + 9
Then apply Distributive Property to left hand side of equation, so now you have:
44 - 4x = x^2 - 6x + 9
Add 4x to both sides:
44 = x^2 -2x + 9
Subtract 44 from both sides:
0 = x^2 - 2x - 35
Another way to put above equation is:
0 = (x + 5)(x - 7)
In order to find x, you set each "set" equal to zero and solve for x:
(x + 5) = 0 (x - 7) = 0
x = -5 x = 7
So the answer is x = -5, 7

4(11 - x) --> 44 - 4x
(x - 3)^2 --> (x - 3)(x - 3) --> x^2 - 3x - 3x + 9 --> x^2 - 6x + 9
44 - 4x = x^2 - 6x + 9
(set equation equal to zero)
0 = x^2 - 2x - 35
(factor the trinomial)
(x - 7)(x + 5)
0 = -5, 7
(x - 3)^2 --> (x - 3)(x - 3) --> x^2 - 3x - 3x + 9 --> x^2 - 6x + 9
44 - 4x = x^2 - 6x + 9
(set equation equal to zero)
0 = x^2 - 2x - 35
(factor the trinomial)
(x - 7)(x + 5)
0 = -5, 7

4(11-x) = (x-3)^2
x=7,-5
x=7,-5

4(11 - x) = (x - 3)^2
44 - 4x = x^2 - 6x + 9
x^2 - 2x - 35 = 0
(x - 7)(x + 5) = 0
x = -5,7
44 - 4x = x^2 - 6x + 9
x^2 - 2x - 35 = 0
(x - 7)(x + 5) = 0
x = -5,7
