simplify (b-9)/((4-sqrt(7)))

simplify

\frac{b - 9}{( 4 - 7 )}

\frac{( 4 + 7 ) ( b - 9 )}{9}

Solution steps

\frac{b - 9}{4 - 7}

Multiply by the conjugate

\frac{4 + 7}{4 + 7}

= \frac{( b - 9 ) ( 4 + 7 )}{( 4 - 7 ) ( 4 + 7 )}

(4 - 7) (4 + 7) = 9

= \frac{( 4 + 7 ) ( b - 9 )}{9}

f (x - 3) - 4

(5 u^{4}) (4 x - 7)

20 x y + (36 x + 40 y)

\frac{( 3 x ^{2} \cdot y ^{3} - 5 a ^{2} \cdot x ^{4} )}{( - 3 x ^{2} )}

\frac{tan ( x )}{tan ^{2} ( x )}
