2X2+5x-12 4+5x-12 -8+5x 5x-8
5x+8=6 5x=6-8 5x=-2 x=-0.4 Absolute value of -0.4=0.4
5x+(6-3x)+8=5x+6-3x+8=2x+14 2x + 14
- 5x - 6y - 8 = 0Add (5x + 8) to each side:- 6y = 5x + 8Divide each side by -6 :y = (-5/6)x - 8/6y = - 5x/6 - 4/3
- 5x - 6y - 8 = 0Add (5x + 8) to each side:- 6y = 5x + 8Divide each side by -6 :y = (-5/6)x - 8/6y = - 5x/6 - 4/3
2X2+5x-12 4+5x-12 -8+5x 5x-8
Discriminant = 52 - 4 x 2 x (-8) = 89
5x+8=6 5x=6-8 5x=-2 x=-0.4 Absolute value of -0.4=0.4
2x2 - 3 = 13 So 2x2 = 16 x2 = 8 So that x = ±2√2
5x+(6-3x)+8=5x+6-3x+8=2x+14 2x + 14
5x-8= -2x+6(+8 = +8)5x=-2x+14(+2x = +2x)7x=14x=14
- 5x - 6y - 8 = 0Add (5x + 8) to each side:- 6y = 5x + 8Divide each side by -6 :y = (-5/6)x - 8/6y = - 5x/6 - 4/3
- 5x - 6y - 8 = 0Add (5x + 8) to each side:- 6y = 5x + 8Divide each side by -6 :y = (-5/6)x - 8/6y = - 5x/6 - 4/3
8 times(2x2 - 5x - 3) = 8(2x + 1)(x - 3)
5x-13x+6=0 5x-13x=-6 -8x=-6 -8x/-8=-6/-8 x = 3/4
2 x 2 + 8 - 6 = 6
The expression is: 6-5x when simplified
