$y=\frac{1}{4\left(x^2-\frac{3}{4}x+\frac{9}{4}\right)}$
Learn how to solve equazioni razionali problems step by step online. y=1/(4x^2-3x+9). Apply the formula: ax^2+bx+c=a\left(x^2+\frac{b}{a}x+\frac{c}{a}\right), where a=4, b=-3 and c=9. Apply the 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), where a=4, b=-\frac{3}{4}x and c=\frac{9}{4}. Apply the 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), where a=4, b=-\frac{3}{4}x, c=\frac{9}{4}, x^2+b=x^2-\frac{3}{4}x+\frac{9}{4}+\frac{9}{64}-\frac{9}{64}, f=\frac{9}{64} and g=-\frac{9}{64}. Apply the formula: \frac{a}{b}c=\frac{ca}{b}, where a=3, b=8, c=-1, a/b=\frac{3}{8} and ca/b=- \frac{3}{8}.
