2x^2 + 3x - 20 = 0 is
2x^2 + 8x - 5x -20 = 0 is
2x(x + 4) -5(x + 4) = 0 is
(2x - 5)(x +4) = 0
Hence 2x -5 = 0 which gives x = 2.5 or x + 4 = 0 which gives x = -4

X squared plus 9 squared equals 12 squared?
X = √63
A squared plus b squared equals c squared?
X squared plus b squared equals c squared when x and b squared equals 5 - 2 what does c equal
When a squared plus b squared equals c squared what is the square root of the square root of the square root of a squared squared squared plus b squared squared squared?
Since a squared plus b squared equals c squared, that is the same as c equals the square root of a squared plus b squared. This can be taken into squaring and square roots to infinity and still equal c, as long as there is the same number of squaring and square roots in the problem. Since this question asks for a and b squared three times, and also three square roots of a and b both, they equal c. Basically, they cancel each other out.

IF 2 plus 3 equals 10. 7 plus 2 equals 63. 6 plus 5 equals 66. 8 plus 4 equals 96 therefore 9 plus 7 equals?
2 squared plus 2 x 3 = 10, 7 squared plus 7 x 2 = 63, 6 squared plus 6 x 5 = 66,8 squared plus 8 x 4 = 96 so 9 squared plus 9 x 7 = 81 + 63 = 144.
