x^2 + y - 3(x + 4)

Step-by-step explanation:

Do one thing at a time until you figure out the entire expression.

the sum of the square of a number x and a number y, minus the product of three times the sum of x and 4

x

the sum of the square of a number x and a number y, minus the product of three times the sum of x and 4

x^2

the sum of the square of a number x and a number y, minus the product of three times the sum of x and 4

x^2 + y

the sum of the square of a number x and a number y, minus the product of three times the sum of x and 4

x^2 + y -

the sum of the square of a number x and a number y, minus the product of three times the sum of x and 4

x^2 + y -     (x + 4)

the sum of the square of a number x and a number y, minus the product of three times the sum of x and 4

x^2 + y - 3(x + 4)
