Converting Expressions to Polynomials

To convert the given expressions into polynomials, we can use the distributive property to expand the products.

1) (3x + 5)(x - 6): - First, we multiply each term in the first expression by each term in the second expression: - 3x * x = 3x^2 - 3x * (-6) = -18x - 5 * x = 5x - 5 * (-6) = -30 - Then, we combine like terms: - 3x^2 - 18x + 5x - 30 - 3x^2 - 13x - 30

2) (2 + y - y^2)(y - 6): - First, we multiply each term in the first expression by each term in the second expression: - 2 * y = 2y - 2 * (-6) = -12 - y * y = y^2 - y * (-6) = -6y - (-y^2) * y = -y^3 - (-y^2) * (-6) = 6y^2 - Then, we combine like terms: - -y^3 + 6y^2 + 2y - 6y - 12 - -y^3 + 6y^2 - 4y - 12

3) (5c + 4)(3c - 5): - First, we multiply each term in the first expression by each term in the second expression: - 5c * 3c = 15c^2 - 5c * (-5) = -25c - 4 * 3c = 12c - 4 * (-5) = -20 - Then, we combine like terms: - 15c^2 - 25c + 12c - 20 - 15c^2 - 13c - 20

So, the expanded forms of the given expressions as polynomials are: 1) 3x^2 - 13x - 30 2) -y^3 + 6y^2 - 4y - 12 3) 15c^2 - 13c - 20
