we know that
The algebraic expression of the phrase " The sum of square of c and d" is equal to adds the square of number c to the number d
[tex](c^{2}+d)[/tex]
The algebraic expression of the phrase " The sum of square of c and d increased by twice their product" is equal to
[tex](c^{2}+d)+2(cd)[/tex]
