Answer 2

Solving the Equations

Let's solve the given equations step by step.

1) (m + n) + 2 = ... - A) m^2 + n^2 - B) m^2 + 2mn + n^2 - C) m^2 + 2mn - n^2

The correct answer is B) m^2 + 2mn + n^2.

2) (2b – c)(2b + c) = ... - A) 2b^2 + c^2 - B) c^2 – 4b^2 - C) 4b^2 – c^2 - D) 2b^2 - c^2

The correct answer is C) 4b^2 – c^2.

3) 24a + 4a^2 + 36 = ... - A) (4a – 6)(6 + 4a) - B) (2a + 6)^2 - C) (2a – 6)^2 - D) (2a – 6)(2a + 6)

The correct answer is A) (4a – 6)(6 + 4a).
