Direction: Determine whether each mathematical sentence is a quadratic inequality or not. Color the thing with a quadratic inequality attached to it
1) 12x²-6x + 10 = 24
2) 7x² = x -2
3) (x - 2) (x + 2) ≥ 10
4) 2 + + 1 ≤ +²
5) 3x (x - 2) < 5
6) x² - 5 + 6 ≥ 10
7) 5y²+ 2y - 2 < 12
8) (x - 2) (x + 2) > x³
9) (2x+1) (x+2) = 6
10) x< 5
