Solve the equation

Question

(5y+8z)^2

Answer 1

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
