Question

(m-4)(m+2)-(m-2)^2 помогите плиииииииииииз

Answer 1

(m-4)(m+2)-(m-2)²=2m-12
1) (m-4)(m+2)=m²+2m-4m-8=m²-2m-8
2) (m-2)²=(m-2)(m-2)=m²-2m-2m+4=m²-4m+4
3) m²-2m-8-(m²-4m+4)=m²-2m-8-m²+4m-4=2m-12

Answer 2

(m-4)(m+2)-(m-2)²=m²-2m-8-m²+4m-4=2m-12=2(m-6)

Answer 3

I can help you with your math problem. Here is the detailed solution:

(m-4)(m+2)-(m-2)^2 = m^2 - 2m - 8 - (m^2 - 4m + 4) // Expand the brackets = m^2 - 2m - 8 - m^2 + 4m - 4 // Distribute the negative sign = -2m - 12 + 4m // Combine like terms = 2m - 12 // Simplify

The final answer is 2m - 12. I hope this helps.Ответь+подробно.+(m-4)(m+2)-(m-2)^2+помогите+плиииииииииииз
