Learning Task 3. Solve for the variable of the following quadratic equations A. by extracting square roots. 1. x2 = 169 4. (x - 2)2 = 16 2. 9b2 = 25 5. 2(t-3)2 - 72 = 0 3. (3y - 1)2 = 0 B. by factoring 1. x2 + 7x = 0 3. x2 + 5x - 14 = 0 2. m2 + 8m = -16 4. 2y2 +8y - 10= 0 C. by completing the square. 1. x2 + 5x + 6= 0 + 60 2. x2 + 2x = 8 3. 2x2 + 2x = 24 D. using quadratic formula. 1. x2 + 5x = 14 2. 2x2 +8x - 10= 0 3. 2x2 + 3x = 27 A​
