WebTalk the Talk The discriminant is the expression b2 - 4 ac, which is defined for any quadratic equation ax2 + bx + c = 0. Based upon the sign of the expression, you can determine how many real number solutions the quadratic equation has. Here's how the discriminant works. Web16 mrt. 2024 · Method 1: Using the direct formula Using the below quadratic formula we can find the root of the quadratic equation . There are following important cases. If b*b < 4*a*c, then roots are complex (not real). For example roots of x2 + x + 1, roots are -0.5 + i1.73205 and -0.5 - i1.73205 If b*b == 4*a*c, then roots are real and both roots are same.

WebFor a quadratic equation ax 2 + bx + c = 0, The roots are calculated using the formula, x = (-b ± √ (b 2 - 4ac) )/2a. Discriminant is, D = b 2 - 4ac. If D > 0, then the equation has two real and distinct roots. If D < 0, the equation has two complex roots. If D = 0, the equation has only one real root. Sum of the roots = -b/a WebFind the Discriminant b^2-4ac=4. b2 − 4ac = 4 b 2 - 4 a c = 4. Subtract 4 4 from both sides of the equation. b2 − 4ac−4 = 0 b 2 - 4 a c - 4 = 0. The discriminant of a quadratic is the expression inside the radical of the quadratic formula. b2 − 4(ac) b 2 - 4 ( a c) Substitute in the values of a a, b b, and c c. self propelled vehicle examples
