Concept of discriminant to classify roots of quadratic equation
Understand the concept of discriminant to classify roots of quadratic equation as real and distinct and also as real and equal.
- if one of the zeroes of quadratic polynomial F(x) = 4x² - 8kx - 9 is equal in magnitude but opposite in sign, find K
-
2 x square - 2 root 2 X + 1 is equal to 0
- (x+1)²=2(x-3)
- if alpha and beta are the zeros of the polynomial ax2+bx+c find the value of alpha3+beta3
