⬇️HERE IS YOUR ANSWER⬇️
________________________

STEP 1
we are given a quadratic equation
like
ax²+bx - c = 0
bring the 'c' to rhs

STEP 2
it becomes ax² + bx = c

STEP 3
we then add (b/2)² on both the sides as shown
ax² + bx + (b/2)²= c + (b/2)²

STEP 4
we then notice that the lhs part make the identity, so we make it in the simpler form
(a + b) ² identity

(ax+b/2)²= c + b²/4

STEP 5
now, take the lcm of the rhs
(ax+b/2)²= (4c + b²)/4

now evaluate the equation both sides
