180=11x+9x. 180 = 20x. 18=2x. 9=x.
6x^2 + 11x + 4 is a Quadratic Statement. It is NOT an equation, because there is no 'equals' (=). It will factor to ( 3x + 4)(2x + 1)
11x(2x - 1) = 0 so either 11x = 0 or x = ½
2x+32 = 1 2x = 1-32 2x = -31 x = -15.5
22+2x = 37+6+x 2x-x = 37+6-22 x = 21
2x + 9x simplified would be 11x
2x + 6 + 9x = 39 11x + 6 = 39 11x = 39 - 6 11x = 33 x = 3
2x2 + 11x + 15 = (x + 3)(2x + 5).
180=11x+9x. 180 = 20x. 18=2x. 9=x.
2x - 13 x = 24 -11x = 24 -11x/-11 = 24/-11 x = -2 2/11
13x + 15 = 11x - 5 2x = -20 x = -10
6x^2 + 11x + 4 is a Quadratic Statement. It is NOT an equation, because there is no 'equals' (=). It will factor to ( 3x + 4)(2x + 1)
