How do you find the roots of an equation?
The roots of a quadratic equation ax2 + bx + c = 0 can be found using the quadratic formula that says x = (-b ± √ (b2 - 4ac)) /2a. Alternatively, if the quadratic expression is factorable, then we can factor it and set the factors to zero to find the roots.
How to find the other root of a quadratic equation if one root is given?
The product of the roots of the quadratic equation ax2+bx+c=0 a x 2 + b x + c = 0 is ca . So, in this case, we can find the other root by dividing this product by the given root.
What are real roots?
Real roots. The real roots are expressed as real numbers. Suppose a x 2 + b x + c = 0 is a quadratic equation and D = b 2 – 4 a c is the discriminant of the equation such that: If then the roots of the equation are real and equal numbers. If , then the roots are real and unequal.
