After simplification of the expression, the result is (6y² + 4y + 5) – (3 – 7y + y²) = 5y² +11y +2 and (x-7) (x+3) = x² -4x-21.
What is an Expression?
An expression is a mathematical statement consisting of variables, constants and mathematical operators.
The expression is
(6y² + 4y + 5) – (3 – 7y + y²)
(x-7) (x+3)
To simplify,(6y² + 4y + 5) – (3 – 7y + y²)
= (6y² + 4y + 5) – (3 – 7y + y²)
= 6y² + 4y + 5 - 3+ 7y - y²
= 5y² +11y +2
To simplify, (x-7) (x+3)
= (x-7) (x+3)
= x² -7x +3x -21
= x² -4x-21
The complete question is
Simplify each of the expressions. (6y^2 + 4y + 5) – (3 – 7y + y^2)
(x-7) (x+3)
