### What does quadratic formula give us?

To convert it to standard form, we need to take a few steps:

• 3x 2 + 7x – 3 = x 2 + 2x + 6 [original equation]
• 2x 2 + 7x – 3 = 2x + 6 [after subtracting x 2 from both sides]
• 2x 2 + 5x – 3 = 6 [after subtracting 2x from both sides]
• 2x 2 + 5x – 9 = 0 [after subtracting 6 from both sides]
