Find the roots of quadratic eqution 4x²-12x -9=0​

Answer»

APPROPRIATE EQUATION

4x²- 12x + 9 = 0

To Find

The roots of quadratic eqution.

SOLUTION

4x²- 12x + 9 = 0

Splitting the middle term,

=> 4x² - 6X - 6x + 9 = 0

=> 2x(2x - 3) - 3(2x - 3) = 0

=> (2x - 3)(2x - 3) = 0

=> 2x - 3 = 0

=> X = 3/2.

or,

=> 2x - 3 = 0

=> x = 3/2.

The roots of the equation

4x²- 12x + 9 = 0 is 2/3.
