Question 41109: Find the roots of the quadratic equations using the quadratic formula. Express the roots, if they are not rational, in simplest radicl form.
You can put this solution on YOUR website! 4x^2 - 12x - 7 = 0 yields
x = (12 ± sqrt(144+112)) / 8
x = (12 ± sqrt(256)) / 8
x = (12 ± 16) / 8
x = 28 / 8 = 7/2 and
x = -4 / 8 = -1/2
