x2+12x+5 = 3 x2+12x+5-3 = 0 x2+12x+2 = 0
x=5
30+12x = 6(5+2x)
8x-3+6x-1 = 12x+614x-4 = 12x+614x-12x = 6+42x = 10x = 5
2x+5=-91-10x 12x+5=-91 12x=-96 x=-8
x2+12x+5 = 3 x2+12x+5-3 = 0 x2+12x+2 = 0
x=5
30+12x = 6(5+2x)
17
8x-3+6x-1 = 12x+614x-4 = 12x+614x-12x = 6+42x = 10x = 5
2x+5=-91-10x 12x+5=-91 12x=-96 x=-8
6x+7 = -56x = -12x = -2
4x2 - 12x + 9 = 5; whence, 2x - 3 = ±√5, and 2x = 3 ±√5. Therefore, x = ½ (3 ±√5).
x=5/2*sqr(3)
(-3, -5)
18x + 45 or 9(2x + 5) how is this answer figured?
x works out as 5/3
