Answer:
x = 10, -15
Step-by-step explanation:
We can start right away by dividing both sides of our equation by 5 to get the reduced form .
To "complete the square," or turn the left side of the equation into something we can factor into a perfect square, it helps to remember that for any binomial x - a:
To "complete" our square, we'll need to add an a² to either side of the equation. To find <em>a</em>, we can set 5x = 2ax and solve:
Let's add that a² to both sides and simplify!
Now we're ready to solve for both value of x:
So our solutions are x = 10 and x = -15
