What is the discriminant of quadratic equation x2 + 11x + 121 = x + 96?
Solution:
Given: Quadratic equation is x2 + 11x + 121 = x + 96
We have to find the discriminant of x2 + 11x + 121 = x + 96
We know that the discriminant of ax2 + bx + c = 0 is given by b2 - 4ac.
⇒ x2 + 11x + 121 = x + 96
By transposing we get,
⇒ x2 + 11x - x + 121 - 96 = 0
⇒ x2 + 10 x + 25 = 0
Where, a = 1 , b = 10 and c = 25
The discriminant of ax2 + bx + c = 0 is b2 - 4ac
= 102 - 4(1)(25)
= 100 - 100 = 0
Therefore, the discriminant of the quadratic equation is 0.
What is the discriminant of quadratic equation x2 + 11x + 121 = x + 96?
Summary:
The discriminant of the quadratic equation x2 + 11x + 121 = x + 96 is 0.
