(5x - 1)(x + 3)5x2 + 14x - 3= 5x2 + 15x - x - 3= 5x(x + 3) - 1(x + 3)= (5x - 1)(x + 3)
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)
It can be simplified to: -14x+8 or 8-14x
10 + 14x - 3 is pretty much the same thing as 7 + 14x. You can't solve this problem without knowing what x is or what the equation equals out to. For example, if 10 + 14x - 3 = 21, x would equal 1.
x2 + 14x + 48 = (x + 8)(x + 6)
(x - 2)(5x + 24)
(5x - 1)(x + 3)5x2 + 14x - 3= 5x2 + 15x - x - 3= 5x(x + 3) - 1(x + 3)= (5x - 1)(x + 3)
(5x - 1)(x + 3)

Improved answer:5x2+14x+5 = 5-5x2+14x+5 = 0Solve by completing the square:(x+7)2+5 = 0(x+7)2+5-49 = 0(x+7)2 = 44x+7 = + or - the square root of 44x = -7 + or - the square root of 44
Distance travelled = 5x3 - 6x2 + 3x + 14 = 5x3 + 5x2 - 11x2 - 11x + 14x + 14 = 5x2(x + 1) - 11x(x + 1) + 14(x + 1) = (x + 1)(5x2 - 11x + 14) Then time = distance/rate = (x + 1)(5x2 - 11x + 14) / (x+1) = 5x2 - 11x + 14
3x2+14x+8 = 0 x = -2/3 or x = -4
If you mean: -5x+14x = 48+14 then 9x = 62 and the value of x equals 62/9 = 6.'8' recurring '8'
