factor 9x^2-y^2+4y-4

factor

9 x^{2} - y^{2} + 4 y - 4

(3 x + y - 2) (3 x - y + 2)

Solution steps

9 x^{2} - y^{2} + 4 y - 4

Factor

- y^{2} + 4 y - 4 : - (y - 2)^{2}

= 9 x^{2} - (y - 2)^{2}

Simplify

9 x^{2} : (3 x)^{2}

= (3 x)^{2} - (y - 2)^{2}

Apply Difference of Two Squares Formula:

x^{2} - y^{2} = (x + y) (x - y)

(3 x)^{2} - (y - 2)^{2} = (3 x + (y - 2)) (3 x - (y - 2))

= (3 x + (y - 2)) (3 x - (y - 2))

Simplify

(3 x + (y - 2)) (3 x - (y - 2)) : (3 x + y - 2) (3 x - y + 2)

= (3 x + y - 2) (3 x - y + 2)

49 m^{2} - 16 x^{4}

\frac{x}{( a - a ^{2} - x ^{2} )}

- 3.2 - 5 x - 2

(x + 2 y)^{3} + 512

5.8 x \cdot 105 \cdot 4 \cdot 3 \cdot 1064
