Question

If the discriminant of the equation 2x^2-7x+p=0 is 33, the value of p is

Answer 1

Answer:

discriminant of 2x^2 -7x +p =0

is (coefficient of x)^2 -4(coefficient of x^2)(constant)

So, 7^2 -4(2)p = 33(given)

49 -8P = 33

8p =49-33

8p = 16

p=2

Answer 2

Answer:

discriminant = b² -4ac

=> (-7)² -4 × 2 × p = 33

=> 49 - 8p = 33

=> 49 - 33 = 8p

=> 16 = 8p

=> p = 16/8 = 2

so, p = 2
