Question

What's the value of x ?


`\hookrightarrow \tt \: x {}^(2) + 4 = 0`
​

Answer 1

this equation has no real solution

Explanation:

x² + 4 = 0

x² = -4

x = ± √−4

this equation has no real solution

Answer 2

`\large \implies \boxed{ \bf \red{x = ± √( - 4) } \\ }`

Step-by-step explanation :

`\bf\longrightarrow {x}^(2) + 4 = 0 \\ \\ \bf\longrightarrow {x}^(2) = 0 - 4 \\ \\\bf\longrightarrow {x}^(2) = - 4 \\ \\\bf\longrightarrow x = ± √( - 4)`
