Ill freind you on Fortnite just give me epic name

Evaluate the discriminant of each equation. tell how many solutions each equation has and whether the solutions are real or imaginary. 4x^2 + 20x + 25 = 0

Solve each quadratic equation by factoring and using the zero product property. x^2 - 8x + 30 = 3x

What value is a discontinuity of x squared plus 8 x plus 4, all over x squared minus x minus 6?
