x^2-5x-24=0 is solved by factoring.
(x+3)(x-8)=0
x+3=0
x=-3
x-8=0
x=8
5x + 70 = 5 (x + 14)
If you mean: 5x+35 then when factored it is 5(x+7)
6x2+5x+1 = (3x+1)(2x+1) when factored
X(5-8)
No solution.
2x2 + 5x = x*(2x + 5)
(x - 3)(x - 2)
20x + 4 = 4(5x + 1)
It is: x(5+1)
(2x+1)(x+2) = 0
(4+x) (2x-3)
(2x - 1)(x + 3)
