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
= $\frac{8 \sqrt{7}-4 \sqrt{6} }{22}$

Answer:

$\sqrt{29}$

Step-by-step explanation:

Use the distance formula!

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

If we plug in the coordinates:

$d=\sqrt{(3-(-2))^2+(4-2)^2} \\d=\sqrt{25+4}\\ d=\sqrt{29}$

That's our answer!

Identify the following equation as that of a line, a circle, an ellipse, a parabola, or a hyperbola. x^2 + 2y^2 = 2

Sergeu [11.5K]

This is an equation representing the ellipse

Explanation:

The general equation for an ellipse is $\frac{x^{2} }{a^{2} } + \frac{y^{2} }{b^{2} } = 1$ so, when you simplify it according to the characteristics of a and b, you would end up in the similar form of the equation given
