don't know but I'll help u please follow me

Answer 2

Step-by-step explanation:

ax ² + bx + c where a ≠ 0

In other words, a quadratic equation must have a squared term as its highest power

Examples of quadratic equations

y = 2x² + 3x + 5

y = 13x² + 22

y = x² − 4x +5

y = −x² + 5

Examples of equations that are NOT quadratic

y = 11x + 22

y = x3 − 4x² +5x +6

y = 2x3 − 7x²

y = −x4 + 5
