Datrys (6x)+(7x)(6x)+6(7x)+x(7x)

$$( 6 x ) + ( 7 x ) ( 6 x ) + 6 ( 7 x ) + x ( 7 x )$$

Enrhifo

$$x\left(49x+48\right)$$

Camau Ateb

Lluosi x a x i gael x^{2}.

$$6x+7x^{2}\times 6+6\times 7x+x\times 7x$$

Lluosi x a x i gael x^{2}.

$$6x+7x^{2}\times 6+6\times 7x+x^{2}\times 7$$

Lluosi 7 a 6 i gael 42.

$$6x+42x^{2}+6\times 7x+x^{2}\times 7$$

Lluosi 6 a 7 i gael 42.

$$6x+42x^{2}+42x+x^{2}\times 7$$

Cyfuno 6x a 42x i gael 48x.

$$48x+42x^{2}+x^{2}\times 7$$

Cyfuno 42x^{2} a x^{2}\times 7 i gael 49x^{2}.

$$48x+49x^{2}$$

Ffactor

$$x\left(49x+48\right)$$

Camau Ateb

Ffactora allan x.

$$x\left(48+49x\right)$$

Ystyriwch 6+42x+42+7x. Lluosi a chyfuno termau sydd yr un fath.

$$49x+48$$

Ailysgrifennwch y mynegiad cyfan wedi'i ffactorio.

$$x\left(49x+48\right)$$
