Question

Wat does f(x)=x^2+x-30 solve to?

Answer 1

F(X) = 5 or -6

Explanation:

F(X) =
`x^(2) +x-30`

Using the Formula

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

Where a = coefficient of
`x^(2)` i. e 1

b = coefficient of
`x` i. e 1

And c = 30

imputing the values, we have

`-1` ±
`\frac{\sqrt{1^(2) - 4 X 1 X 30} }{2 X 1}`

`-1` ±
`(√(121) )/(2)`

`-1+(11)/(2)` OR
`-1-(11)/(2)`

Therefore, F(X) is either 5 or -6
