Can someone please help me solve this problem

Step-by-step explanation:

Step 1:  After adding 875 to both sides of the original equation, you get

Step 2: b is the coefficient of the x term, so b = 10.  Divide in half (always half for completing the square!).

Square that result to get 25.  That's c, the amount to add to both sides of the equation.

Step 3:  Adding c to both sides produces

Step 4: The result of Step 3 is , and the left side factors as a perfect square.

Step 5: After taking square roots of both sides, you get

 which represents "two equations in one."
