(x - 2)(x - 3) = 2
x^2 - 3x - 2x + 6 = 2
x^2 - 5x + 4 = 0
(x - 1)(x - 4) = 0
x = 1 or x = 4
The solution set of (x - 2)(x - 3) = 2 is {1, 4}

2x(x - 1) = 3
2x^2 - 2x - 3 = 0
a = 2, b = -2, c = -3
b^2 - 4ac = (-2)^2 - 4(2)(-3) = 4 + 24 = 28
x = (2 ± sqrt 28)/4
= (2 ± 2 sqrt 7)/4
= (1 ± sqrt 7)/2

y(y + 4)(y - 6) = 0 is a quadratic equation. FALSE.
y(y + 4)(y - 6) = 0
y(y^2 - 2y - 24) = 0
y^3 - 2y^3 - 24y = 0 which is not a quadratic equation.

y(y + 4) - y = 6 is a quadratic equation. True.
y(y + 4) - y = 6
y^2 + 4y - y = 6
y^2 + 3y - 6 = 0 which is a quadratic equation.

Twenty pounds of a salt-water solution contains fifteen percent salt. How much salt is in the water? 1.5 lb 2 lb 3 lb
Weegy: 15% of 20 is 3, so twenty pounds of a salt-water solution that contains fifteen percent salt contains 3 lb of salt. User: Twenty pounds of a salt-water solution contains fifteen percent salt. How much water must be added to weaken the solution to twelve percent salt? 3 lb 5 lb 12 lb Weegy: There is 3 lb of salt in the 20 lb of solution. If 3 lb is to be 12%, 100% is (3/12) x 100 = 25 lb in total. So 5 lb of water needs to be added. (More)
