X=-4 is the answer because all of the points of the line are x=-4
Step-by-step explanation:
Given bi-quadratic equation is:
Substituting
given bi-quadratic equation reduces in the form of following quadratic equation:
Let us factorize the above quadratic equation:
Since square root of a negative number cannot be found, so:

6h+1-h+3
=5h+4
because 6h-1h is 5h and 1+3 is 4
