I need to know how to simplify using conjugate

liubo4ka [24]

$\frac{4}{2 \sqrt{7}+ \sqrt{6} }$
Multiply denominator and numerator of fraction by conjugate (2√7 -6)
= $\frac{4(2 \sqrt{7})(- \sqrt{6}) }{(2 \sqrt{7} + \sqrt{6})(2 \sqrt{7} - \sqrt{6} ) }$
Expand using distributive property
= $\frac{8 \sqrt{7}- 4 \sqrt{6} }{28-2 \sqrt{42}+2 \sqrt{42} -6 }$
Collect like terms to simplify
= $\frac{8 \sqrt{7}-4 \sqrt{6} }{22}$

Hello from MrBillDoesMath!

Answer:

y = x/15

Discussion:

Given:

2x/5y = 6 => (multiply both sides by 5y)

(2x/5y) 5y = 6 * (5y) =>

2x = 30y => (divide both sides by 30)

(2/30)x = y =>

y = x/15

( or you could also multiply both sides of the original equation by "y" and then divide both sides by 6)

Thank you,

MrB
