factor 4x^2y^2-4x^2-49y^2+49

factor

4 x^{2} y^{2} - 4 x^{2} - 49 y^{2} + 49

(y + 1) (y - 1) (2 x + 7) (2 x - 7)

Solution steps

4 x^{2} y^{2} - 4 x^{2} - 49 y^{2} + 49

= (4 x^{2} y^{2} - 4 x^{2}) + (- 49 y^{2} + 49)

Factor out

4 x^{2}

from

4 x^{2} y^{2} - 4 x^{2} : 4 x^{2} (y^{2} - 1)

Factor out

- 49

from

- 49 y^{2} + 49 : - 49 (y^{2} - 1)

= 4 x^{2} (y^{2} - 1) - 49 (y^{2} - 1)

Factor out common term

y^{2} - 1

= (y^{2} - 1) (4 x^{2} - 49)

Factor

y^{2} - 1 : (y + 1) (y - 1)

= (y + 1) (y - 1) (4 x^{2} - 49)

Factor

4 x^{2} - 49 : (2 x + 7) (2 x - 7)

= (y + 1) (y - 1) (2 x + 7) (2 x - 7)

\frac{3}{5} x = 10

x^{2} - 6 x - 5 = 0

\frac{7 π}{6} - 2 π

\frac{4}{2 + 2} + \frac{1}{3 - 2 2}

3 x^{2} - 2 x - 7 = 0
