Explanation:

Use the formula

(b/2)2 in order to create a new term. Solve for x by using this term to complete the square.

Exact Form: x= ± √101/2+ 1/2

Decimal Form: x=5.52493781…,−4.52493781...

Hope this helps

Answer:

x = 5.52, -4.52.

Explanation:

x^2 - x = 25

(x - 0.5)^2 - 0.25 = 25

(x - 0.5)^2 = 25.25

x - 0.5 = +/- √25.25

x = 0.5 +/- √25.25

x = 5.52, -4.52.
