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 equation4x²- 12x + 9 = 0 is 2/3. |
