factor 3/(8+sqrt(7))

factor

\frac{3}{8 + 7}

\frac{8 - 7}{19}

Solution steps

\frac{3}{8 + 7}

Multiply by the conjugate

\frac{8 - 7}{8 - 7}

= \frac{3 ( 8 - 7 )}{( 8 + 7 ) ( 8 - 7 )}

(8 + 7) (8 - 7) = 57

= \frac{3 ( 8 - 7 )}{57}

Cancel the common factor:

3

= \frac{8 - 7}{19}

(cos (2 π x))^{2}

2 a - 6 b + a c - 3 b c

52

(a + 2)^{2} - 8 + a^{3} - 2 a

x^{8} - 9
