Solution

factor

49 k^{4} - 9

Solution

(7 k^{2} + 3) (7 k^{2} - 3)

Solution steps

49 k^{4} - 9

Apply exponent rules

= (7 k^{2})^{2} - 3^{2}

Apply Difference of Two Squares Formula:

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

(7 k^{2})^{2} - 3^{2} = (7 k^{2} + 3) (7 k^{2} - 3)

= (7 k^{2} + 3) (7 k^{2} - 3)
