Does the following quadratic equation have a maximum or minimum value? How can you tell?
y=x²+2x-3

• Minimum value, because the a value is positive
• Maximum value, because the b value is positive
• Maximum value, because the a value is positive
• Minimum value, because the c value is negative

Solve. Factoring would be the easiest, but you may use any algebraic method. x²=18x-81

• x= -9, -9

• x= 9, 9

• x= -9, 9

Put 2x² = 3x - 4 in standard form

• 2x² + 3x - 4 = 0
• 2x² - 3x + 4 = 0
• 2x² - 3x - 4 = 0
• 2x² + 3x + 4 = 0
