Now keeping this in mind, we can solve the inequality by squaring both the sides: x + 2 ≥ x2. So x2 − x − 2 ≤ 0. Solving, (x − 2)(x + 1) ≤ 0. Therefore x belongs to the interval [ − 1, 2]. As x ≥ − 2, the function is also defined.

If a given number is … WebMar 27, 2024 · 2. Take the square roots of your perfect square factors. The product property of square roots states that for any given numbers a and b, Sqrt (a × b) = Sqrt (a) × Sqrt (b). Because of this property, we can now take the square roots of our perfect square factors and multiply them together to get our answer. [3]
WebMost square root equations can be solved in a way similar to this, by trying to get a least one square root term along on a side, then squaring it.
