Exercise
$\left(\frac{3}{8}x^2+\frac{1}{4}x-\frac{2}{5}\right)\:por\:2x^3-\frac{1}{3}x+2$
Step-by-step Solution
Learn how to solve problems step by step online. Expand the expression (3/8x^2+1/4x-2/5)2x^3-1/3x+2. Solve the product 2\left(\frac{3}{8}x^2+\frac{1}{4}x-\frac{2}{5}\right)x^3. Multiply the fraction and term in 2\cdot \left(\frac{3}{8}\right)x^2. Multiply 2 times 3. Divide 6 by 8.
Expand the expression (3/8x^2+1/4x-2/5)2x^3-1/3x+2
Final answer to the exercise
$\frac{3}{4}x^{5}+\frac{1}{2}x^{4}+\left(-\frac{4}{5}\right)x^3-\frac{1}{3}x+2$
