Q. Express the area of the entire rectangle.Your answer should be a polynomial in standard form.
Multiply Length and Width: To find the area of a rectangle, we need to multiply the length by the width.
Represent Length and Width: Let's say the length of the rectangle is represented by the polynomial 3x+4, and the width is represented by the polynomial x−2.
Multiply Polynomials: Now, we multiply the two polynomials: (3x+4)(x−2).
Apply Distributive Property: Using the distributive property (FOIL), we get: 3x×x+3x×(−2)+4×x+4×(−2).
Simplify Expression: Simplify the expression: 3x2−6x+4x−8.
Combine Like Terms: Combine like terms: 3x2−2x−8.
Standard Form: The polynomial is already in standard form, which is written with terms in descending order of degree.
