2x2 + 7x - 15 = (2x - 3)(x + 5)
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.
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)
2x2 + 7x + 6 = 2x2 + 4x + 3x + 6 = 2x(x + 2) + 3(x + 2) = (x + 2)(2x + 3)
2x2 + 7x - 15 = (2x - 3)(x + 5)
X squared + 7X + 12?
14x2 - 39x - 35 = (7x + 5)(2x - 7)
7x-x2 = x(7-x)
When you subtract 7x^2 from 5x^2, you get -2x^2.
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.
13X squared + 7X + 12

If you mean: 6x^2 +7x-3 then it is (2x+3)(3x-1) when factored
