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