Datrys 0.5(x+h)^2-(x+h)+3

$$0.5 ( x + h ) ^ { 2 } - ( x + h ) + 3$$

Enrhifo

$$\frac{\left(x+h\right)^{2}}{2}-h-x+3$$

Camau Ateb

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

$$0.5\left(x^{2}+2xh+h^{2}\right)-\left(x+h\right)+3$$

Defnyddio’r briodwedd ddosbarthu i luosi 0.5 â x^{2}+2xh+h^{2}.

$$0.5x^{2}+xh+0.5h^{2}-\left(x+h\right)+3$$

I ddod o hyd i wrthwyneb x+h, dewch o hyd i wrthwyneb pob term.

$$0.5x^{2}+xh+0.5h^{2}-x-h+3$$

Ehangu

$$hx+\frac{h^{2}}{2}+\frac{x^{2}}{2}-h-x+3$$
