User: What is the solution set of 2x(x - 1) = 3?

Weegy: 2x + 3 = x - 5;

2x - x = -5 - 3;

x = -8

User: What is the solution set of 7x 2 + 3x = 0? {0, 3/7} {0, -3/7} {0, -4/7}

Weegy: hat depends on whether you mean (2/3)x or 2/(3x). will do them both For (2/3)x = 8, x = 8 (3/2) = 4 3 = 12 If you meant 2/(3x) = 8 then cross-multiply like this: 2 .... 8 - - = - - 3x ...1 2(1) = 8(3x) 2 = 24x so x = 2/24 = 1/12

User: What is the solution set of 7x 2 + 3x = 0?

Weegy: 7x + 4 + 3x -3

= 7x + 3x + 4 - 3

= 10x + 1

= 10x

User: What is the solution set of (x - 2)(x - 3) = 2? {1, 4} {2, 3} {4, 5}

User: The square of a certain negative number is equal to five more than one-half of that number. What is the number? -1/2 -5/2 -2

Weegy: x^2 = 0.5x + 5 Quadratic formula gives solutions as: -2 and 2.5, but since x is negative, it's -2.

User: The width and the length of a rectangle are consecutive even integers. If the width is decreased by 3 inches, then the area of the resulting rectangle is 24 square inches. What is the area of the original rectangle? 12 square inches 48 square inches 96 square inches

Weegy: The width and the length of a rectangle are consecutive even integers. If the width is decreased by 3 inches, then the area of the resulting rectangle is 24 square inches. What is the area of the original rectangle? B. [ 48 square inches ]

2x(x - 1) = 3
2x^2 - 2x - 3 = 0
b^2 - 4ac = (-2)^2 - 4(2)(-3) = 28
x = [-b ± sqrt (b^2 - 4ac)]/2a
= (2 ± sqrt 28)/4
= (2 ± 2 sqrt 7)/4
= (1 ± sqrt 7)/2

7x^2 + 3x = 0
x(7x + 3) = 0
x = 0 or x = -3/7
The solution set for 7x^2 + 3x = 0 is {0, -3/7}.

(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 for (x - 2)(x - 3) = 2 is {1, 4}
