factor 49x^4-4y^2

factor

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

(7 x^{2} + 2 y) (7 x^{2} - 2 y)

Solution steps

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

49 x^{4} = (7 x^{2})^{2}

4 y^{2} = (2 y)^{2}

= (7 x^{2})^{2} - (2 y)^{2}

Apply Difference of Two Squares Formula:

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

(7 x^{2})^{2} - (2 y)^{2} = (7 x^{2} + 2 y) (7 x^{2} - 2 y)

= (7 x^{2} + 2 y) (7 x^{2} - 2 y)

\frac{( x + y ) ^{3} - x ^{3}}{y}

100 + 8 - (- 8)

6 i - (14 - i) + (5 - 3 i)

∣ 1 - 3 ∣

5 k + 3 k^{3} + 7 k + 9 k^{3}
