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.
