You simplify the left side
Answer:
Lesser x is -13.
Greater x is 1.
Step-by-step explanation:
We have the function:
And we want to find the zeros of the function.
So, set f(x) to 0 and solve for x:
Add 49 to both sides:
Take the square root of both sides. Since we're taking an even root, we will need plus/minus:
Subtract 6 from both sides:
Evaluate for each case:
Case 1; 7 is positive:
Case 2; 7 is negative:
So, our zeros are:
Our lesser x is -13, and our greater x is 1.
And we're done!
