Question

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

Answer 1

Answer:

F(X) = 5 or -6

Step-by-step 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

$-1$ ± $\frac{\sqrt{1^{2} - 4 X 1 X 30} }{2 X 1}$

$-1$ ± $\frac{\sqrt{121} }{2}$

$-1+\frac{11}{2}$ OR $-1-\frac{11}{2}$

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