factor 7x^4-343y^4

factor

7 x^{4} - 343 y^{4}

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

Solution steps

7 x^{4} - 343 y^{4}

Factor out common term

7 : 7 (x^{4} - 49 y^{4})

= 7 (x^{4} - 49 y^{4})

Factor

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

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

- \frac{4}{7} \cdot 2

(4 x^{\frac{1}{2}})^{2}

\frac{b ^{2} - ab}{a - b}

4 - ∣ 3 x + 6 ∣ = 1

5 x^{2} + 500 = 0
