The instruction "solve" means to determine the value of the variable that makes the equation true. You do not present an equation.
 
You could request to square the binomial.
 
(5y + 8z)2
(5y + 8z)(5y + 8z)    definition of exponent
(5y)(5y) +(5y)(8z) + (8z)(5y) + (8z)(8z)     FOIL
25y2 + 40yz + 40yz + 64z2                         Simplify
25y2 + 80yz + 64z2                                    combine like terms
