What is the nature of the roots of the equation 2×2 3x 4 0?
Answer: The roots are real and distinct.
Which of the following is the value of discriminant for √ 2×2 5x+ √ 2 0?
Step-by-step explanation: the value of discriminant is 17.
What is the value of k for which the quadratic equation 3x 2 KX k 0 has equal roots?
For equal roots of the given quadratic equations, Discriminant will be equal to 0. Therefore, the values of k for which the quadratic equation 3x 2−2kx+12=0 will have equal roots are 6 and −6.
What is the sum to product formula?
The sum-to-product formulas allow us to express sums of sine or cosine as products. These formulas can be derived from the product-to-sum identities. For example, with a few substitutions, we can derive the sum-to-product identity for sine. Let u + v 2 = α u + v 2 = α and.
How many real roots does b2 – 4 A C = 0?
When b 2 − 4 a c = 0 there is one real root. When b 2 − 4 a c > 0 there are two real roots. When b 2 − 4 a c < 0 there are two complex roots. is used to solve quadratic equations where a ≠ 0 (polynomials with an order of 2) Example 1: Find the Solution for x 2 + − 8 x + 5 = 0 , where a = 1, b = -8 and c = 5, using the Quadratic Formula.
How many real roots does X2 + – 8 x + 5?
Example 1: Find the Solution for x 2 + − 8 x + 5 = 0 , where a = 1, b = -8 and c = 5, using the Quadratic Formula. The discriminant b 2 − 4 a c > 0 so, there are two real roots.
