Impara online a risolvere i problemi di completare il quadrato passo dopo passo. Solve the equation y=15+3x-x^2. Applicare la formula: ax^2+bx+c=a\left(x^2+\frac{b}{a}x+\frac{c}{a}\right), dove a=-1, b=3 e c=15. Applicare la formula: a\left(x^2+b+c\right)=a\left(x^2+b+c+\left(\frac{coef\left(b\right)}{2}\right)^2-\left(\frac{coef\left(b\right)}{2}\right)^2\right), dove a=-1, b=-3x e c=-15. Applicare la formula: a\left(x^2+b+c+f+g\right)=a\left(\left(x+\sqrt{f}sign\left(b\right)\right)^2+c+g\right), dove a=-1, b=-3x, c=-15, x^2+b=x^2-3x-15+\frac{9}{4}-\frac{9}{4}, f=\frac{9}{4} e g=-\frac{9}{4}. Applicare la formula: \frac{a}{b}+c=\frac{a+cb}{b}, dove a/b+c=\left(x- \frac{3}{2}\right)^2-15-\frac{9}{4}, a=-9, b=4, c=-15 e a/b=-\frac{9}{4}.
