$y=3\left(x^2+\frac{5}{3}x+\frac{8}{3}\right)$
Learn how to solve problems step by step online. Solve the equation y=3x^2+5x+8. Apply the formula: ax^2+bx+c=a\left(x^2+\frac{b}{a}x+\frac{c}{a}\right), where a=3, b=5 and c=8. 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{5}{3}x and c=\frac{8}{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{5}{3}x, c=\frac{8}{3}, x^2+b=x^2+\frac{5}{3}x+\frac{8}{3}+\frac{25}{36}-\frac{25}{36}, f=\frac{25}{36} and g=-\frac{25}{36}. The least common multiple (LCM) of a sum of algebraic fractions consists of the product of the common factors with the greatest exponent, and the uncommon factors.
