which of the following quadratic equations can be solved easily by extracting square roots A. x² + 7x + 12 = 0 B. 3t + 7x –3 = 0 C. 3x² + 2x – 8 = 0D. 4x² – 9 = 0
Answer (1)
Answer:The quadratic equation that can be solved easily by extracting square roots is d. 4x² – 9 = 0. Step-by-step explanation:1.) Add 9 to both sides: 4x² = 92.) Divide both sides by 4: x² = 9/43.) Take the square root of both sides: x = ±√(9/4)4.) Simplify: x = ±(3/2)hope it helps you somehow
