3x+4 = 5x-6 3x-5x = -6-4 -2x = -10 x = 5
3x + 7 = 5x + 13 3x - 5x = 13 - 7 -2x = 6 -x = 3 x = -3
3x - 5x + x = -x
X=-3
The discriminant b2-4ac is -23
x = 25 / 3squared + 5
2x+3x = 5x
5x = 3x+1000+0 5x-3x = 1000 2x = 1000 x = 500
5x - 4 = 3x + 6 5x - 3x = 6 + 4 2x = 10 x = 5
5x+3 = 3x+11 5x-3x = 11-3 2x = 8 x = 4
5x3 - 3x2 + 2x = x*(5x2 - 3x + 2) The quadratic has no real factors.
3x+11+5x=75(add 5x and 3x) 8x+11=75(-11) 8x=64(/ 8) x=8(ANSWER)
