factor 49x^4-64

factor

49 x^{4} - 64

(7 x^{2} + 8) (7 x^{2} - 8)

Solution steps

49 x^{4} - 64

Apply exponent rules

= (7 x^{2})^{2} - 8^{2}

Apply Difference of Two Squares Formula:

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

(7 x^{2})^{2} - 8^{2} = (7 x^{2} + 8) (7 x^{2} - 8)

= (7 x^{2} + 8) (7 x^{2} - 8)

\frac{12 !}{2 ! ( 12 - 2 ) !}

10 x^{2} + 6 x + 1 = 0

- 4 m + 21 (m - 1) \leq 15 m + 2 (m - 1)

0 \geq \frac{5 - x}{2} \geq - 10

\frac{( n + 2 ) !}{( n + 1 ) !}
