The solution tot he quadratic equation is: x = -3/8 or 1/8
The method that Janice used was to substitute 64x² and 16x with B² and 2B respectively
How to solve the quadratic equation?
The quadratic equation is given as:
0 = 64x² + 16x - 3
Line 2: 0 = B² + 2B - 3
Line 3: 0 = (B + 3)(B - 1)
Where B = 8x
Thus:
8x + 3 = 0
8x - 1 - 0
x = -3/8 or 1/8
