(5x 2 - 8x + 1) + (2x 2 - 4x - 11)
2(3x + 4) + 5x - 2
5x + 4 = 3x - 2Subtract 4 from both sides:5x = 3x - 6Subtract 2x from both sides:2x = 6Divide both sides by 2:x = -3
x2+5x+6 = (x+2)(x+3)
2
(2x + 1)(x + 2)
(2x + 1)(x + 2)
2(5x + 3y)(2x + 5y)
(x - 2)(2x + 9)
3x + 5x = 2x + 28x = 2x + 26x = 2x = (2/6) = 1/3
20x2 + 22xy + 6y2 = 20x2 + 10xy + 12xy + 6y2 = 10x(2x + y) + 6y(2x + y) = (2x + y)(10x + 6y) = 2(2x + y)(5x + 3y)
2x +1 = 5x-2 2x +3= 5x 3 = 3x x=1
x+2x+14=5x+214-2=5x+2x+x10=8x10/8=xx=5/4 ans.
x=6Solution:x + 2x + 14 = 5x + 214 - 2 = 5x - 3x12 = 2xx = 12/2 = 6
5x+2=2x-10 x=-4
8x-7 plus 2x equals 6 plus 5x plus 2?
-2x+7x=5x. Factor out the x. -2+7 I hope you know how to use a calculator. :D
