Question: Work out the discriminant for each equation and then determine whether each equation has two distinct roots, equal roots or no real roots. a) 2x
Work out the discriminant for each equation and then determine whether each equation has two distinct roots, equal roots or no real roots.
a) 2x² – 3x + 4 = 0
b) 5x² – 11x + 4 = 0 -
c) x² + 12x + 36 = 0
d) 2x² + x – 2 = 0
e) 4x² + 5x + 2 = 0
f) 4x² – 12x + 9 = 0
g) 7x² – 2x + 1 = 0
h) x² – 6x + 7 = 0
i) 2x – 4x² = 0
j) 6x² = 6x – 1
k) 16x² = 24x – 9
l) (x + 2)² – 8x – 2 = 0
