2x +1 = 5x-2 2x +3= 5x 3 = 3x x=1
2x2+5x+3 = (2x+3)(x+1) when factored
(2x + 3)(x + 1 ) = 2x^2 +5x +3
(2x + 1)(x + 2)
(2x+3)/(10x2+21x+9)Factor the quadratic expression in the denominator:(2x+3)/(5x+3)(2x+3)which becomes:1/(5x+3) or (5x+3)-1
2x +1 = 5x-2 2x +3= 5x 3 = 3x x=1
6 + 2x = 5x + 9 , 6 - 9 = 5x - 2x , -3 = 3x , x = -1
3x + 5x = 2x + 28x = 2x + 26x = 2x = (2/6) = 1/3
If that was 2x^2 + 5x + 2, it would factor to (2x + 1)(x + 2)
2x2+5x+3 = (2x+3)(x+1) when factored
(2x + 3)(x + 1 ) = 2x^2 +5x +3
x=1 2/3 How?: 2x-4+3 = 5x-6 2x-1 = 5x-6 2x-1+1 = 5x-6+1 2x = 5x-5 2x-5x = 5x-5x-5 -3x = -5 -3x/-3 = -5/-3 x = 5/3 x = 1 2/3
5x+2x=7x2x + 5x = 7x
6x^2 + 5x + 1 = (3x +1) (2x + 1)
2x plus 5x simplified is 7x.
(5x 2 - 8x + 1) + (2x 2 - 4x - 11)
(2x + 1)(x + 2)
