Question

Use factorisation method to find the roots of 3 (x^2-4)=5x

Answer 1

Answer:

Given 3x

Given 3x 2

Given 3x 2 −5x+2=0

Given 3x 2 −5x+2=0Here, the coefficient of x

Given 3x 2 −5x+2=0Here, the coefficient of x 2

Given 3x 2 −5x+2=0Here, the coefficient of x 2 is 3 and it is not a perfect square.

multiply the equation throughout by 3.

ltiply the equation throughout by 3.⇒(3x

ltiply the equation throughout by 3.⇒(3x 2

ltiply the equation throughout by 3.⇒(3x 2 −5x+2=0)×3∴9x

ltiply the equation throughout by 3.⇒(3x 2 −5x+2=0)×3∴9x 2

ltiply the equation throughout by 3.⇒(3x 2 −5x+2=0)×3∴9x 2 −15x+6=0
