Datrys (x-1)^2(x+9)^2

$$( x - 1 ) ^ { 2 } ( x + 9 ) ^ { 2 }$$

Enrhifo

$$\left(\left(x-1\right)\left(x+9\right)\right)^{2}$$

Camau Ateb

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

$$\left(x^{2}-2x+1\right)\left(x+9\right)^{2}$$

Defnyddio'r theorem binomaidd \left(a+b\right)^{2}=a^{2}+2ab+b^{2} i ehangu'r \left(x+9\right)^{2}.

$$\left(x^{2}-2x+1\right)\left(x^{2}+18x+81\right)$$

Defnyddio’r briodwedd ddosbarthu i luosi x^{2}-2x+1 â x^{2}+18x+81 a chyfuno termau tebyg.

$$x^{4}+16x^{3}+46x^{2}-144x+81$$

Ehangu

$$x^{4}+16x^{3}+46x^{2}-144x+81$$
