Solve x^2+10x+5=0 using completing the square.

Completing the square is one of the 3 common ways to solve a quadratric equation (other two being factorising and using the quadratic formula).Using completing the square method, you manipulate the first two terms (x²+10x). This is done by putting these two in a bracket and squaring the bracket. First you divide the 2nd term (10x) by 2 and and create a bracket so that it is (x+5When you expand thi s
