$${ \left(x-1 \right) }^{ 2 } { \left(x+4 \right) }^{ 2 }$$

Enrhifo

$$\left(\left(x-1\right)\left(x+4\right)\right)^{2}$$

Camau Ateb

Defnyddio'r theorem binomaidd \left(a-b\right)^{2}=a^{2}-2ab+b^{2} i ehangu'r \left(x-1\right)^{2}.

$$\left(x^{2}-2x+1\right)\left(x+4\right)^{2}$$

Defnyddio'r theorem binomaidd \left(a+b\right)^{2}=a^{2}+2ab+b^{2} i ehangu'r \left(x+4\right)^{2}.

$$\left(x^{2}-2x+1\right)\left(x^{2}+8x+16\right)$$

Defnyddio’r briodwedd ddosbarthu i luosi x^{2}-2x+1 â x^{2}+8x+16 a chyfuno termau tebyg.

$$x^{4}+6x^{3}-24x+x^{2}+16$$

Ehangu

$$x^{4}+6x^{3}+x^{2}-24x+16$$
