The answer of given equation is [tex]2c^{2}[/tex] + 5c +4

Step-by-step explanation:

By putting the given values of E and F we get,

E + F

=( [tex]6c^{2}-2c-1[/tex]) + (-[tex]4c^{2}+7c+5[/tex])

Here we will take the coefficient of same variable together

=([tex]6c^{2}-4c^{2}[/tex]) +( -2c +7c) +( -1+5)

=[tex]2c^{2}[/tex] + 5c +4

Hope this helps you.
