Who can solve by factoring and using the principle of zero products show all work for 4x2-12x equals 16?
1. Subtract 16 from each side: 4x2 -12x - 16 = 0
2. Divide by 4: 4 ( x2 - 3x - 4) = 0
3. What factors of -4 total -3? -4 and 1
4. Full factors are thus: 4.(x + 1)(x - 4) = 0
5. One of these expressions must equal zero; it obviously isn't 4 so it must be (x + 1) or (x - 4)
6. x is therefore either -1 or 4
