Question

2] Expand (m - 4)(m + 6)​

Answer 1

Answer:

m²+2m-24

Step-by-step explanation:

(m-4) (m+6)

= m²+6m-4m-24

= m²+2m-24

Answer 2

Answer:

Let us simplify the expression, we get

(m – 4) (m + 6) = m2 + [(- 4) + (6)] m + [(- 4) × (6)]

By using the logic,

(x + p) (x + q) = x2 + (p + q)x + (p × q)

Here, x = m, p = -4, q = 6

Now, substitute the value we get

= m2 + (6 – 4)m + (- 24)

= m2 + 6m – 4m – 24

= m2 + 2m – 24

∴ (m – 4) (m + 6) = m2 + 2m – 24
