(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}

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

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) = 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.

y(y + 4) - y = 6

y^2 + 4y - y = 6

y^2 + 3y - 6 = 0 which is a quadratic equation.

1 = 2x^2 + 7x

2x^2 + 7x - 1 = 0

a = 2, b = 7, c = -1

b^2 - 4ac = 7^2 - 4(2)(-1) = 49 + 8 = 57

2x^2 + 7x - 1 = 0

a = 2, b = 7, c = -1

b^2 - 4ac = 7^2 - 4(2)(-1) = 49 + 8 = 57

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)
