Quadratic Equations Definition & Examples Expii
A Quadratic Equation Of The Form 0 Ax2 Bx C. No real root if d is negative i.e. X = −b ± √(b 2 − 4ac) 2a;
Positive, there are 2 real solutions; Ax 2 + bx + c = 0; 2 equal real roots if d=0. Quadratic equations can be factored; When the discriminant (b 2 −4ac) is: 2 unequal real solutions if d is positive i.e. Web quadratic equation in standard form: No real root if d is negative i.e. X = −b ± √(b 2 − 4ac) 2a;
