5x2+ 7x + 2 = (x + 1)(5x + 2).
If you mean 5x^2 -7x +2 = 0 then it is a quadratic equation with solutions of x = 2/5 or x = 1
7x + 2
5x + 17 = 7x - 123 123 + 17 = 7x - 5x 140 = 2x x = 140 ÷ 2 x = 70
35x^2 + 77x + 42
5x2+ 7x + 2 = (x + 1)(5x + 2).
When you subtract 7x^2 from 5x^2, you get -2x^2.
If you mean 5x^2 -7x +2 = 0 then it is a quadratic equation with solutions of x = 2/5 or x = 1
-12x-2Given: -5x-(7x+2)This is the same as -5x-1(7x+2). Use the distributive property and multiply the -1 through (7x+2).-5x-7x-2Simplify.-12x-2
((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)
7x + 2
5x + 17 = 7x - 123 123 + 17 = 7x - 5x 140 = 2x x = 140 ÷ 2 x = 70
7x + 12 = 5x + 2 Subtract '12' from both sides Hence 7x = 5x -10 Subtract '5x' from both sides. 2x = -10 Divide both sides by '2' Hence x = -5 .
5x-7x = -2
