You can put this solution on YOUR website!
(2x+1)^2+x(2x-9)-5=0
4x^2 + 4x + 1 + 2x^2 - 9x - 5 = 0
6x^2 - 5x - 4 = 0 Format: a^2 + bx + c
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
x+=+%285+%2B-+sqrt%28+121+%29%29%2F%2812%29+
x+=+%285+%2B-+11%29%2F%2812%29+
x = -6/12, x = 16/12
x = -1/2, 4/3
