Answer 2

Equation

Question:

 (m+3)(m-4)

Step by Step Explanation

• (m+3)(m-4)
• We will open the bracket
• $m^{2} - 4m + 3m - 12$
• $m^{2} - m - 12$
• So, now we have the quadratic equation.
• We can also use the identity to solve this question

• $(x + a)(x + b) = x^{2} + (a + b)x + ab$

• Here,
• x = m
• a = 3
• b = -4
• So, you can put these values in above identity
