ax² + bx + c = 0
A) 4 + 3x = 4x + 1
4x - 3x = 4 - 1
x = 3
b) 4(x + 1) = 6(x - 1)
4x + 4 = 6x - 6
6x - 4x = 6 + 4
2x = 10
x = 10 / 2
x = 5
c) 2(x - 3) = 14 + 7(x + 1)
2x - 6 = 14 + 7x + 7
7x - 2x = 21 + 6
5x = 27
x = 27 / 5
d) 10x + 2x + 5 = 3x + 2x - 12
12x + 5 = 5x - 12
12x - 5x = - 12 - 5
7x = - 17
x = - 17 / 7.
