Question

find the value of p if the equation x^2+ px+36=0 has equal roots​

Answer 1

Answer:

p = ±12

Step-by-step explanation:

For equal roots, D = 0

As we know, D = b² - 4ac

Quadratic equation: x² + px + 36 = 0

From the given quadratic equation,

a = 1

b = p

c = 36

So, b² - 4ac = 0

(p)² - 4 (1) (36) = 0

p² = 144

p = ±12

or, p = -12, +12
