The square-5x-12 of solving inequality 2x is less than or equal to 0

The square-5x-12 of solving inequality 2x is less than or equal to 0


2x²-5x-12≤0
(2x+3)(x-4)≤0
The solution is - 3 / 2 ≤ x ≤ 4



The set of Nonnegative Solutions of inequality 2x square + 5x-12 less than or equal to 0 is


2x^2+5x-12≤0
(2x-3)(x+4)≤0
-4≤x≤3/2
The set of nonnegative solutions is [0,3 / 2]



|X-3 | + (y + 1) · (y + 1) = 0 find 3x-2y =?


|X-3 | > = 0 (y + 1) ^ 2 > = 0 and their sum is 0, so x-3 = 0, x = 3; y + 1 = 0, y = - 1, 3x-2y = 3 * 3-2 (- 1) = 9 + 2 = 11
