Question

4x²-1
25x²-0,09
9x²-1/4

Answer 1

\(4x^2-1=\left(2x-1\right)\left(2x+1\right)\\ 25x^2-0,09=\left(5x-0,3\right)\left(5x+0,3\right)\\ 9x^2-\dfrac{1}{4}=\left(3x-\dfrac{1}{2}\right)\left(3x+\dfrac{1}{2}\right)\)

Answer 2

\(4x^2-1=\left(2x-1\right)\left(2x+1\right)\)

\(25x^2-0.09=\left(5x-0.3\right)\left(5x+0.3\right)\)

\(9x^2-\dfrac{1}{4}=\left(3x-\dfrac{1}{2}\right)\left(3x+\dfrac{1}{2}\right)\)
