Solve: 2x² - 5x - 7 = 0 (no calculator)

• x = 1, x = -7/2

• x = 7/2, x = -1

• x = -1/2, x = 7

• x = 1/2, x = -7

Solve: 4x² = 25 (no calculator)

• x = 3

• x = 5/2

• x = 5/2, x = -5/2

• x = 5/4, x = - 5/4

Solve the following equation (no calculator). Hint: factor

x⁴ + x² - 90 = 0

• 3, -3, ±i√10

• 3, -3, 10, -10

• ±√10, 3, -3

• 3 multiplicity 4
