To solve first move the 98 to the other side by subtracting it from both sides. Then divide by - 1 on both sides to that the x^2 is no longer a negative. You are left with:

x^{2} = 98

Now square root both sides to get

x = +/-  \sqrt{98}

The two factors that make up 98 are 49 and 2. 49 can be square rooted. So we are left with these answers:

x = - 7 \sqrt{2} and x = 7 \sqrt{2}

If f(x)= x2 + 5, and g(x) = 3x - 11, find (g(f(-3)).
fgiga [73]

Answer:

31

Step-by-step explanation:

first find f(-3)

f(-3) = (-3)^2 +5

       = 9+5 = 14

The find g(f(-3) = g(14)

                         = 3*14-11

                           = 42-11

                             =31
