Question

Mark as right (√ )or wrong (× ): 1.If b2 -4ac> 0,then equation will have two distinct real roots. 2. In quadratic equation ax2 + bx + c = 0, b2 -4ac is known as Discriminant. 3.The nature of roots of quadratic equation x2 -5x-7 = 0 are real and equal.

Answer 1

Step-by-step explanation:

To determine the nature of roots of quadratic equations (in the form ax^2 + bx +c=0) , we need to caclulate the discriminant, which is b^2 - 4 a c. When discriminant is greater than zero, the roots are unequal and real. When discriminant is equal to zero, the roots are equal and real.
