Réitigh (3(-24/29)-2)^2=(-24/29-5)(9(-24/29)+4)

$$( 3 ( \frac { - 24 } { 29 } ) - 2 ) ^ { 2 } = ( \frac { - 24 } { 29 } - 5 ) ( 9 ( \frac { - 24 } { 29 } ) + 4 )$$

Céimeanna Réitigh

Is féidir an codán \frac{-24}{29} a athscríobh mar -\frac{24}{29} ach an comhartha diúltach a bhaint.

$$\left(3\left(-\frac{24}{29}\right)-2\right)^{2}=\left(\frac{-24}{29}-5\right)\left(9\times \frac{-24}{29}+4\right)$$

Méadaigh 3 agus -\frac{24}{29} chun -\frac{72}{29} a fháil.

$$\left(-\frac{72}{29}-2\right)^{2}=\left(\frac{-24}{29}-5\right)\left(9\times \frac{-24}{29}+4\right)$$

Dealaigh 2 ó -\frac{72}{29} chun -\frac{130}{29} a fháil.

$$\left(-\frac{130}{29}\right)^{2}=\left(\frac{-24}{29}-5\right)\left(9\times \frac{-24}{29}+4\right)$$

Ríomh cumhacht -\frac{130}{29} de 2 agus faigh \frac{16900}{841}.

$$\frac{16900}{841}=\left(\frac{-24}{29}-5\right)\left(9\times \frac{-24}{29}+4\right)$$

Is féidir an codán \frac{-24}{29} a athscríobh mar -\frac{24}{29} ach an comhartha diúltach a bhaint.

$$\frac{16900}{841}=\left(-\frac{24}{29}-5\right)\left(9\times \frac{-24}{29}+4\right)$$

Dealaigh 5 ó -\frac{24}{29} chun -\frac{169}{29} a fháil.

$$\frac{16900}{841}=-\frac{169}{29}\left(9\times \frac{-24}{29}+4\right)$$

Is féidir an codán \frac{-24}{29} a athscríobh mar -\frac{24}{29} ach an comhartha diúltach a bhaint.

$$\frac{16900}{841}=-\frac{169}{29}\left(9\left(-\frac{24}{29}\right)+4\right)$$

Méadaigh 9 agus -\frac{24}{29} chun -\frac{216}{29} a fháil.

$$\frac{16900}{841}=-\frac{169}{29}\left(-\frac{216}{29}+4\right)$$

Suimigh -\frac{216}{29} agus 4 chun -\frac{100}{29} a fháil.

$$\frac{16900}{841}=-\frac{169}{29}\left(-\frac{100}{29}\right)$$

Méadaigh -\frac{169}{29} agus -\frac{100}{29} chun \frac{16900}{841} a fháil.

$$\frac{16900}{841}=\frac{16900}{841}$$

Cuir \frac{16900}{841} agus \frac{16900}{841} i gcomparáid lena chéile.
