I. 8x² + 2x – 3 = 0 8x² + 6x - 4x – 3 = 0 2x (4x + 3) – 1(4x + 3) = 0 (2x – 1) (4x + 3) = 0 x = 1/2, -3/4 II. 6y² + 11y + 4 = 0 6y² + 8y + 3y + 4 = 0 2y(3y + 4) + 1(3y + 4) = 0 (2y + 1) (3y + 4) = 0 y = - 1/2, -4/3 Hence, no relationship can be established between x and y
11.89 × 2.10 × 4.98 × 4.03 ÷ 7.98 of 15.03 = ?
9.8 × 77.9 ÷ (2.3)2= ?
26.23 × 31.82 + 44.8% of 1200 + ? = 1520
15.1 + 3.97 – 9.07 × 1.96 = √?
? = 49.99² ÷ (1.98⁵ + 8.01 × 89.91) + 75.15% of (263.89 × 49.11)
