How to solve negative square root
WebUse the Quadratic Formula: x = −2 ± √ (−16) 10 √ (−16) = 4 i (where i is the imaginary number √−1) So: x = −2 ± 4i 10 Answer: x = −0.2 ± 0.4 i The graph does not cross the x-axis. That is why we ended up with complex numbers. In a way it is easier: we don't need more calculation, we leave it as −0.2 ± 0.4i. Example: Solve x 2 − 4x + 6.25 = 0 WebMar 18, 2024 · We can use this rule for radicals to simplify the expression: √a ⋅ b = √a ⋅ √b √4 ⋅ 2 ⋅ −1 ⇒ √4 ⋅ √2 ⋅ √−1 ⇒ 2√2 ⋅ √−1 The symbol i which is an imaginary number is another way to write: √−1 so we can rewrite the expression as: 2√2 ⋅ i ⇒ 2i√2 If necessary we can approximate √2 as 1.414 and get: 2 ⋅ 1.414i ⇒ 2.828i Answer link
