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

factor

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

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

Solution steps

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

Factor

x^{2} + 4 x + 4 : (x + 2)^{2}

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

Apply Difference of Two Squares Formula:

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

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

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

Apply rule:

(a) = a

(x + 2) = x + 2

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

\frac{18}{90}

- \frac{1}{4} + \frac{1}{4}

\frac{y ^{2}}{y ^{4}}

- 9 (- 5 - 4 c)
