PYQ NEET- Problem On Quadratic Equations

• Question: Solve 4x2 - 12x + 9 = 0.

• Answer: x = 3, -1.

• Year: 2017.

This is a quadratic equation in standard form. We can solve it using the quadratic formula:

x = (-b ± √(b^2 - 4ac)) / 2a

In this case, a = 4, b = -12, and c = 9. Substituting these values into the quadratic formula, we get:

x = (-(-12) ± √((-12)^2 - 4(4)(9))) / (2*4)

x = (12 ± √(144 - 144)) / 8

x = (12 ± 0) / 8

x = 12 / 8 = 1.5

x = -12 / 8 = -1.5

Therefore, the conclusion is that
