Simplify the expression: (3x + 2y) + (4x - 3y)

  1. 7x - y

  2. 7x + y

  3. 7x - 5y

  4. 7x + 5y

Show answer
Correct Option: A
Explanation:

Combine like terms: (3x + 4x) + (2y - 3y) = 7x - y.

Simplify the expression: (2a^2 + 3ab) - (a^2 - 2ab)

  1. a^2 + 5ab

  2. a^2 - 5ab

  3. 3a^2 + 5ab

  4. 3a^2 - 5ab

Show answer
Correct Option: C
Explanation:

Combine like terms: (2a^2 - a^2) + (3ab + 2ab) = a^2 + 5ab.

Simplify the expression: (x + 3)(x - 2)

  1. x^2 + x - 6

  2. x^2 - x - 6

  3. x^2 + 5x - 6

  4. x^2 - 5x - 6

Show answer
Correct Option: A
Explanation:

Use the distributive property: (x + 3)(x - 2) = x^2 - 2x + 3x - 6 = x^2 + x - 6.

Simplify the expression: (2x^2y^3)(3xy^2)

  1. 6x^3y^5

  2. 6x^3y^6

  3. 6x^2y^5

  4. 6x^2y^6

Show answer
Correct Option: A
Explanation:

Multiply the coefficients and combine like terms: (2x^2y^3)(3xy^2) = 6x^3y^5.

Simplify the expression: (a + b)^2

  1. a^2 + 2ab + b^2

  2. a^2 - 2ab + b^2

  3. a^2 + b^2

  4. a^2 - b^2

Show answer
Correct Option: A
Explanation:

Use the formula for squaring a binomial: (a + b)^2 = a^2 + 2ab + b^2.

Simplify the expression: (x - 3)^3

  1. x^3 - 9x^2 + 27x - 27

  2. x^3 + 9x^2 + 27x + 27

  3. x^3 - 9x^2 - 27x - 27

  4. x^3 + 9x^2 - 27x + 27

Show answer
Correct Option: A
Explanation:

Use the formula for cubing a binomial: (x - 3)^3 = x^3 - 3x^2(3) + 3x(3^2) - 3^3 = x^3 - 9x^2 + 27x - 27.

Simplify the expression: (2x + 3y)(2x - 3y)

  1. 4x^2 - 9y^2

  2. 4x^2 + 9y^2

  3. 4x^2 - 6xy + 9y^2

  4. 4x^2 + 6xy + 9y^2

Show answer
Correct Option: A
Explanation:

Use the difference of squares formula: (a + b)(a - b) = a^2 - b^2.

Simplify the expression: (a^2 + 2ab + b^2) - (a^2 - 2ab + b^2)

  1. 4ab

  2. 2ab

  3. 0

  4. 4a^2

Show answer
Correct Option: A
Explanation:

Combine like terms: (a^2 + 2ab + b^2) - (a^2 - 2ab + b^2) = a^2 + 2ab + b^2 - a^2 + 2ab - b^2 = 4ab.

Simplify the expression: (x^2 - 4)(x^2 + 4)

  1. x^4 - 16

  2. x^4 + 16

  3. x^4 - 8x^2 + 16

  4. x^4 + 8x^2 + 16

Show answer
Correct Option: A
Explanation:

Use the difference of squares formula: (a + b)(a - b) = a^2 - b^2.

Simplify the expression: (3a - 2b)^2

  1. 9a^2 - 12ab + 4b^2

  2. 9a^2 + 12ab + 4b^2

  3. 9a^2 - 6ab + 4b^2

  4. 9a^2 + 6ab + 4b^2

Show answer
