Whakaoti i te -5/4a^2-3/2ab+1/2a^2+5ab-3a^2-1/2ab

$$- \frac { 5 } { 4 } a ^ { 2 } - \frac { 3 } { 2 } a b + \frac { 1 } { 2 } a ^ { 2 } + 5 a b - 3 a ^ { 2 } - \frac { 1 } { 2 } a b$$

Aromātai

$$\frac{3a\left(4b-5a\right)}{4}$$

Ngā Upane Otinga

Pahekotia te -\frac{5}{4}a^{2} me \frac{1}{2}a^{2}, ka -\frac{3}{4}a^{2}.

$$-\frac{3}{4}a^{2}-\frac{3}{2}ab+5ab-3a^{2}-\frac{1}{2}ab$$

Pahekotia te -\frac{3}{2}ab me 5ab, ka \frac{7}{2}ab.

$$-\frac{3}{4}a^{2}+\frac{7}{2}ab-3a^{2}-\frac{1}{2}ab$$

Pahekotia te -\frac{3}{4}a^{2} me -3a^{2}, ka -\frac{15}{4}a^{2}.

$$-\frac{15}{4}a^{2}+\frac{7}{2}ab-\frac{1}{2}ab$$

Pahekotia te \frac{7}{2}ab me -\frac{1}{2}ab, ka 3ab.

$$-\frac{15}{4}a^{2}+3ab$$

Tauwehe

$$\frac{3a\left(4b-5a\right)}{4}$$

Ngā Upane Otinga

Tauwehea te \frac{1}{4}.

$$\frac{-5a^{2}-6ab+2a^{2}+20ab-12a^{2}-2ab}{4}$$

Whakaarohia te -5a^{2}-6ab+2a^{2}+20ab-12a^{2}-2ab. Tauwehea te a.

$$a\left(-5a-6b+2a+20b-12a-2b\right)$$

Whakaarohia te -5a-6b+2a+20b-12a-2b. Whakarea ka paheko i ngā kīanga tau ōrite.

$$-15a+12b$$

Whakaarohia te -15a+12b. Tauwehea te 3.

$$3\left(-5a+4b\right)$$

Me tuhi anō te kīanga whakatauwehe katoa.

$$\frac{3a\left(-5a+4b\right)}{4}$$
