Question

for what value of p,x-3 is a root of equation px^2+2x-3=0​

Answer 1

Answer:

- 1/3

Step-by-step explanation:

As x - 3 is a root of the given equation it must satisfy all the condition which x satisfies. So, when x = 3,

⇒ p(3)^2 + 2(3) - 3 must be 0

⇒ 9p + 6 - 3 = 0

⇒ 9p + 3 = 0

⇒ 9p = - 3

⇒ p = -3/9

⇒ p = - 1/3
