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

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

Evalwa

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

Passi tas-Soluzzjonijiet

Uża teorema binomjali \left(a+b\right)^{2}=a^{2}+2ab+b^{2} biex tespandi \left(x+h\right)^{2}.

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

Uża l-propjetà distributtiva biex timmultiplika 0.5 b'x^{2}+2xh+h^{2}.

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

Biex issib l-oppost ta' x+h, sib l-oppost ta' kull terminu.

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