\left(\frac{1}{4}x+\frac{1}{4}\left(-1\right)\right)\left(x+7\right)
Whakamahia te āhuatanga tohatoha hei whakarea te \frac{1}{4} ki te x-1.
\left(\frac{1}{4}x-\frac{1}{4}\right)\left(x+7\right)
Whakareatia te \frac{1}{4} ki te -1, ka -\frac{1}{4}.
\frac{1}{4}xx+\frac{1}{4}x\times 7-\frac{1}{4}x-\frac{1}{4}\times 7
Me hoatu te āhuatanga tohatoha mā te whakarea ia tau o \frac{1}{4}x-\frac{1}{4} ki ia tau o x+7.
\frac{1}{4}x^{2}+\frac{1}{4}x\times 7-\frac{1}{4}x-\frac{1}{4}\times 7
Whakareatia te x ki te x, ka x^{2}.
\frac{1}{4}x^{2}+\frac{7}{4}x-\frac{1}{4}x-\frac{1}{4}\times 7
Whakareatia te \frac{1}{4} ki te 7, ka \frac{7}{4}.
\frac{1}{4}x^{2}+\frac{3}{2}x-\frac{1}{4}\times 7
Pahekotia te \frac{7}{4}x me -\frac{1}{4}x, ka \frac{3}{2}x.
\frac{1}{4}x^{2}+\frac{3}{2}x+\frac{-7}{4}
Tuhia te -\frac{1}{4}\times 7 hei hautanga kotahi.
\frac{1}{4}x^{2}+\frac{3}{2}x-\frac{7}{4}
Ka taea te hautanga \frac{-7}{4} te tuhi anō ko -\frac{7}{4} mā te tango i te tohu tōraro.
\left(\frac{1}{4}x+\frac{1}{4}\left(-1\right)\right)\left(x+7\right)

\frac{1}{4}xx+\frac{1}{4}x\times 7-\frac{1}{4}x-\frac{1}{4}\times 7
Me hoatu te āhuatanga tohatoha mā te whakarea ia tau o \frac{1}{4}x-\frac{1}{4} ki ia tau o x+7.
\frac{1}{4}x^{2}+\frac{1}{4}x\times 7-\frac{1}{4}x-\frac{1}{4}\times 7
Whakareatia te x ki te x, ka x^{2}.
\frac{1}{4}x^{2}+\frac{7}{4}x-\frac{1}{4}x-\frac{1}{4}\times 7
Whakareatia te \frac{1}{4} ki te 7, ka \frac{7}{4}.
\frac{1}{4}x^{2}+\frac{3}{2}x-\frac{1}{4}\times 7
Pahekotia te \frac{7}{4}x me -\frac{1}{4}x, ka \frac{3}{2}x.
\frac{1}{4}x^{2}+\frac{3}{2}x+\frac{-7}{4}
Tuhia te -\frac{1}{4}\times 7 hei hautanga kotahi.
\frac{1}{4}x^{2}+\frac{3}{2}x-\frac{7}{4}
Ka taea te hautanga \frac{-7}{4} te tuhi anō ko -\frac{7}{4} mā te tango i te tohu tōraro.
