Question

Solve.

x2+7x+3=0




x=7±37√2



x=7±61√2



x=−7±37√2



x=−7±61√2

Answer 1

`x = ( - 7± √(37) )/(2)`

Explanation:

`{x}^(2) + 7x + 3 = 0`

`\frac{ - b± \sqrt{ {b}^(2) - 4(ac) } }{2a}`

`\frac{ - 7± \sqrt{ {7}^(2) - 4(1 * 3)} }{2 * 1}`

`x = ( - 7± √(37) )/(2 * 1)`

`x = ( - 7± √(37) )/(2)`
