Solve by factoring 5.3 tri a=1

The standard form of a quadratic function is

• ax² + bx + c = 0

• a(x - h)² + k = 0

• y = (x - p)(x - q)

• Ax + By = C

Write the quadratic equation in standard form:

x² + 6x + 9 = 0

• x² + 6x = 9

• Already in standard form

• 7x³ + 9 = 0

• x² + 6x = - 9

Write the quadratic equation in standard form:

-x² = 4x + 3

• Already in standard form

• 0 = 4x + 3 - x²

• -x² + 4x + 3 = 0

• 0 = x² + 4x + 3

Write the quadratic equation in standard form:

x² - 10x = -8

• x² - 2x = 0

• x² - 10x - 8 = 0

• 0 = x² - 10x + 8

• Already in standard form

Factor:

x² + 11x + 24

• (x + 6)(x + 4)

• (x + 12)(x + 2)

• (x - 8)(x - 3)

• (x + 8)(x + 3)

Use Zero Product Property to solve

x² + 2x - 15 = 0

• x = 3 or x = 5

• x = 5 or x = -3

• x = -5 or x = 3

• x = -3 or x = -5

Write an equation in Factored Form, whose solutions are 7 and 3.

• y = (x - 7)(x - 3)

• y = (x + 7)(x + 3)

• y = (x + 7)(x - 3)

• y = (x - 7)(x + 3)
