Question

check whether x= 2/3 is the root of a given quadratic equation 9x^2-3x-2=0​

Answer 1

Answer:

check it in the explanation

Step-by-step explanation:

9x2 – 3x – 2 = 0. ⇒ 9x2 – 3x – 2 = 0. ⇒ 9x2 – 6x + 3x – 2 = 0 ⇒ 3x (3x – 2) + 1(3x – 2) = 0 ⇒ (3x – 2)(3x + 1) = 0 Now, either 3x – 2 = 0 ⇒ x = 2 3 23 Or, 3x + 1= 0 ⇒ x = − 1 3 −13 Thus, the roots of the given quadratic equation are x = 2 3 23 and x = − 1 3 −13 respectively.Read more on Sarthaks.com - https://www.sarthaks.com/646979/find-the-roots-of-the-equation-9x-2-3x-2-0
