Answer:
c = 5
Step-by-step explanation:
Distribute the left side and compare like terms with the right side.
- 2x³(cx³ + x²) = - 2c[tex]x^{6}[/tex] - 2[tex]x^{5}[/tex]
Compare to - 10[tex]x^{6}[/tex] - 2[tex]x^{5}[/tex]
For the 2 sides to equate then
- 2c[tex]x^{6}[/tex] = - 10[tex]x^{6}[/tex]
Hence c = [tex]\frac{-10}{-2}[/tex] = 5
