It equals 53X- a number is squared when it is multiplied by itself, so 7X by 7X = 49X. 2X by 2X =4X, so 49X + 4X is 53X.
2x2 + 7x - 15 = (2x - 3)(x + 5)
7x2 -4x -5x2 +2x = 2x2 -2x
((15xy2)/(x2+5x+6))/((5x2y)/(2x2+7x+3)) =(15xy2/5x2y)*(2x2+7x+3)/(x2+5x+6) =(3y/x)*(((2x+1)(x+3))/((x+2)(x+3) =(3y(2x+1))/(x(x+2)) =(6xy+3y)/(x2+2x)
7 plus 7x--2x plus 3 is: 7 + 7x + 2x + 3 = 0 9x + 10 = 0 9x = -10 x = -10/9 = -1 1/9
You would factor 2x2 + 7x + 6 into (2x + 3) (x+2)
(x + 1)(2x + 5)
(x + 5)(2x - 3)
(x - 2)(2x - 3)
It equals 53X- a number is squared when it is multiplied by itself, so 7X by 7X = 49X. 2X by 2X =4X, so 49X + 4X is 53X.
2x2 + 7x - 15 = (2x - 3)(x + 5)

7x2 -4x -5x2 +2x = 2x2 -2x
When you subtract 7x^2 from 5x^2, you get -2x^2.
