4x^2-5x=0
this equation is in standard form, ax^2+bx+c = 0, though in this particular equation c = 0, like this:
4x^2-5x+0 = 0
So we solve it right away using the quadratic formula, first + and then -:
(-b+-sqrt(b^2-4ac)/2a
x = (-(-5)+sqrt(-5)^2)/2*4
x = (5+(sqrt25))/8
x = (5+5)/8
x = 10/8
x = 5/4
Now for -:
x = (-(-5)-(sqrt(-5)^2)/2*4
x = 5-5/8
x = 0/8 = 0
