Impara online a risolvere i problemi di passo dopo passo. Solve the inequality 4x^2-15x+-11>=0. Applicare la formula: ax^2+bx+c=a\left(x^2+\frac{b}{a}x+\frac{c}{a}\right), dove a=4, b=-15 e c=-11. 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=4, b=-\frac{15}{4}x e c=-\frac{11}{4}. 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=4, b=-\frac{15}{4}x, c=-\frac{11}{4}, x^2+b=x^2-\frac{15}{4}x-\frac{11}{4}+\frac{225}{64}-\frac{225}{64}, f=\frac{225}{64} e g=-\frac{225}{64}. Applicare la formula: \frac{a}{b}c=\frac{ca}{b}, dove a=15, b=8, c=-1, a/b=\frac{15}{8} e ca/b=- \frac{15}{8}.
