Answer 2

Step-by-step explanation:

Given : a

2

−b

2

−4ac+4c

We can write it as

a

2

−b

2

−4ac+4c

=a

2

−4ac+4c

−b

2

So we get

a

2

−b

2

−4ac+4c

=a

2

−2×a×2x+2c

2

−b

2

a

2

−b

2

−4ac+4c

=(a−2c)

2

−b

2

Based on the equation a

2

−b

2

=(a+b)(a−b)

We get,

a

2

−b

2

−4ac+4c

=(a−2c+b)(a−2c−b)
