5x2 - 20xy + 10y2 = 5(x2 - 4xy + 2y2) which cannot be simplified into rational factors.
x = 2 or x = 2/5
5x2y = 3x - 6y 5x2y + 6y = 3x y(5x2 + 6) = 3x y = (3x)/(5x2 + 6) This is a rational function.
5x2-136 = 24 5x2 = 24+136 5x2 = 160 x2 = 32 x = the square root of 32
20 divided by 4 multiplied by 2 plus 6 equals 16. 20/4 = 5, 5x2 = 10, 10+6 = 16.
(x - 2)(5x + 24)
5x2 + 14x - 3 let 14x = 15x - x=5x 2 + 15x - x - 3 factor out 5x and -1 = 5x(x + 3) - 1(x + 3) factor (x + 3) = (x + 3)(5x - 1)
5x2-18x+9 = (5x-3)(x-3)
(5x + 2)(x + 1)
5x2-16x+12 = (5x-6)(x-2) when factored
(5x - 1)(x + 6)
5x2+11x+2 = (5x+1)(x+2) when factored
5x2 - 14x + 8 = 5x2 - 10x - 4x + 8 = 5x(x-2) - 4(x-2) = (5x-4)*(x-2)
5x2+14x-3 -15. 15*-15x2-x+15x-3[5xx x] [3*5x 3]x(5x-1)+3(5x-3)Answer: (5x-1)(x+3)
(5x - 1)(x + 3)5x2 + 14x - 3= 5x2 + 15x - x - 3= 5x(x + 3) - 1(x + 3)= (5x - 1)(x + 3)
5x2+ 7x + 2 = (x + 1)(5x + 2).
5x2 + 3x - 1 does not have rational factors.
