Question

Adiya said that the first step to solving the quadratic equation x2 + 6 = 20x by completing the square was to divide 6 by 2, square that value, and add the result to both sides. Is Adiya’s solution method correct? Explain.

Answer 1

There are two ways to find the solution of quadratic equation.
method 1. completing the square
method 2. using formula.

first we have to arrange the equation in ax^2 +bx + c = 0 form.

then we can solve it.

completing the square may not be applicable for all problems.but solving with formula will really help us.

Hope it helps you.
