Question
SPOT THE ERROR
Maria and Jose wanted to determine the number of real solutions of the
quadratic equation 5x2 - 3x = 2.
Maria
5x2- 3x = 2
b2- 4ac = (-3) - 4(5)(2)
Jose
5x-3x 2
5x - 3x -2 =D0
b-- 4ac = (-3)2 - 4(5)(-2)
= 49
Since the discriminant is 49,
positive and perfect square,
there are two real roots.
= -31
Since the discriminant is -31,
there are no real roots.
