II. q² - 48q + 576 = 0

For what real value(s) of k does the quadratic equation - x² − (k + 3)x + 2k = 0, have equal real roots?

I. x² – 12x + 32 = 0

II. y² + y - 20 = 0

I. 195x² - 46x - 21 = 0

II. 209y² + 13y - 12 = 0

I. x² - (16)² = 0

II. 2y - 14 = 0

Solve for x: |2x − 5| + |x + 1| ≤ 10.

I. 9x² + 45x + 26 = 0
