Question

Write the roots of following quadratic equation.

(p – 5 ) (p + 3 ) = 0​

Answer 1

Answer:

p =5 or p = -3

Step-by-step explanation:

(p-5) (p+3) = 0

p² + 3p - 5p - 15 = 0

p² - 2p - 15 = 0

now by factorization method

p² - 5p + 3p - 15 = 0

p( p - 5 ) + 3( p - 5 ) =0

p - 5 = 0 or p + 3 =0

.°. p= 5 or p = -3
