Impara online a risolvere i problemi di limiti per sostituzione diretta passo dopo passo. Solve the product (1/2x+2/3y)(1/2x-2/3). Applicare la formula: x\left(a+b\right)=xa+xb, dove a=\frac{1}{2}x, b=\frac{2}{3}y, x=\frac{1}{2}x-\frac{2}{3} e a+b=\frac{1}{2}x+\frac{2}{3}y. Applicare la formula: x\left(a+b\right)=xa+xb, dove a=\frac{1}{2}x, b=-\frac{2}{3}, x=\frac{1}{2}x e a+b=\frac{1}{2}x-\frac{2}{3}. Applicare la formula: x\left(a+b\right)=xa+xb, dove a=\frac{1}{2}x, b=-\frac{2}{3}, x=\frac{2}{3}y e a+b=\frac{1}{2}x-\frac{2}{3}. Applicare la formula: \frac{a}{b}\frac{c}{f}=\frac{ac}{bf}, dove a=1, b=2, c=-2, a/b=\frac{1}{2}, f=3, c/f=-\frac{2}{3} e a/bc/f=\frac{1}{2}\cdot -\frac{2}{3}x.
