It can't be solved because the discriminant of this quadratic equation is less than zero
Are you seeking the factors? 7x2 - 10x + 3 = (x - 1)(7x - 3).
2x+8x-2=22 10x-2=22 10x+2=+2 10x=24 10/10=24/10 x=2.4

12x - 6 = 10x +2 12x - 10x = 2 + 6 2x = 8 x = 4
x2-10x-24 = (x+2)(x-12) when factored
20x3 - 70x2 + 60x = 10x(2x2 - 7x + 6) = 10x(2x - 3)(x - 2).
10x - 5x + 5x = 10x
Rearrange: x2 - 10x + 25 = 0ie (x - 5)(x - 5) = 0x = 5Check: x2 = 25; 10x - 25 = 50 - 25 = 25. Job done
It is: 100x^2 -9 = (10x-3)(10x+3) when factored
