x=9 squared
(2x+3)(x+3)
Factor. X^2 + 12X X(X + 12) = 0 X = 0 ------------- X + 12 = 0 X = - 12 --------------
(x+y)2
(x2 + 7x - 18) = (x + 9)(x - 2)
3 squared = 9 4 squared = 16 9 x 16 = 144 3 squared x 4 squared = 144
Add the x's squared together to get 2x^2+x. You cannot add anymore so the answer is 2x^2+x
X = √63
x^2 +9 =x^2 -9 9=-9 No solution
If you mean: x squared -14x +45 then when factored it is (x-9)(x-5)
You can't because it is not a quadratic equation.
(x-3)(x-2)
Solve this problem -x squared -40x- 80 =0
x(x + 9)(x + 1)
x^(2) - 10x + 16 = 0 Factors of '16', which are, 1,2,4,8,16. Select two numbers from this list that add/subtract to '10' . They are '2' and '8'. Setting up brackets ( x 2)(x 8) Since '16' is positive(+), then both signs must be the same. Since '10x' is negative (-) , then both signs are negative. Hence (x - 2)(x - 8 ) = 0 When x - 2 = 0 x = 2 & when x - 8 = 0 x = 8 So the two answers are ,2, & ,8, .
5x squared plus 33x plus 18 = (5x + 3)(x + 6) x = -6, -3/5
(x - 3)(x + 5)
X=1
