simplify (sqrt(7)x^{3n-2}-5)(sqrt(7)x^{3n-2}+9)

simplify

(7 \cdot x^{3 n - 2} - 5) (7 \cdot x^{3 n - 2} + 9)

7 x^{2 (3 n - 2)} + 47 x^{3 n - 2} - 45

Solution steps

(7 x^{3 n - 2} - 5) (7 x^{3 n - 2} + 9)

Apply FOIL method

(7 x^{3 n - 2} - 5) (7 x^{3 n - 2} + 9) : 7 x^{2 (3 n - 2)} + 47 x^{3 n - 2} - 45

= 7 x^{2 (3 n - 2)} + 47 x^{3 n - 2} - 45

4 x^{2} - 9 y^{2} + 20 x + 25

\frac{3}{( x ^{2} - 4 )} + \frac{1}{( x - 2 ) ^{2}}

a^{10} + x^{10}

(i) x^{3} - 2 x^{2} - x + 2

12 x y^{2} - 24 x^{3} y^{3}
