529.

Correct QuestioN :

find the discriminant of the equation x to the power of 2x² +7x -60=0

SolutioN :

We have, Quadratic Equation.

2x² + 7x - 60 = 0.

* Compare With General Equation.

ax² + bx + c = 0.

Where as,

• a = 2.
• b = 7.
• c = - 60.

D = b² - 4ac.

Where as,

• D Discriminate.

D = ( 7 )² - 4 * 2 * - 60

D = 49 + 8 * 60.

D = 49 + 480.

D = 529.

Therefore, the value of D is 529.
