Question

Part of the quadratic formula is shown below. Copy and complete the formula by filling in the gap with the correct expression. For ax² + bx + c = 0 -b± √ x 2a ​

Answer 1

Answer: \[ b^2 - 4ac \]

For the quadratic formula \( ax^2 + bx + c = 0 \), the complete quadratic formula is:

\[ x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \]

So, the expression to fill in the gap is:

\[ b^2 - 4ac \]

Answer 2

Answer:

The completed quadratic formula is:
