Given that f(x) = x2 + 5x – 14 and g(x) = x + 7, find (fºg)(x) and express the result in standard form.

We get

Step-by-step explanation:

We are given:

We need to find

We know that:

We multiply the both terms i.e. f(x) and g(x) to get our answer.

So, we get

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
