Question

Solve this quadratic equation by completing the square x^2+8x=10

Answer 1

n completing method square the first we do is making the coefficient of as one. so in order to make the coefficient as one we divide each term by 7 in given equation

Since, 7 is the coefficient of

Now, if we take 7 as common on left hand side of an equation then it becomes .

Now, we can compare the equation with

Hence, we get the value of A=7.
