Question

I need help please. Solve this plz for A.

Answer 1

Answer:

3(- 6 + m)(- 4 + m)

Step-by-step explanation:

Given

72 - 30m + 3m² ← factor out 3 from each term

= 3(24 - 10m + m²)

To factor the quadratic

Consider the factors of the constant term ( + 24) which sum to give the coefficient of the x- term (- 10)

The factors are - 6 and - 4, since

- 6 × - 4 = 24 and - 6 - 4 = - 10, hence

24 - 10m + m² = (- 6 + m)(- 4 + m) and

72 - 30m + 3m² = 3(- 6 + m)(- 4 + m) ← in factored form
