Question

(m+2)(m-3)= (2x-1)(3x+5)= (4x-3y)(2x-y)= (a-6)(a-1)= (a-2)(a^2-4a+1)= (m-3)(m^2-2m+4)= Помогите пожалуйста срочно нужно:3Решите.

Answer 1

(m+2)(m-3)=m²+2m-3m-6=m²-m-6
(2x-1)(3x+5)=6x²-3x+10x-5=6x²+5x-5
(4x-3y)(2x-y)=8x²-6xy-4xy+3y²=8x²-2xy+3y²
(a-6)(a-1)=a²-6a-a+6=a²-7a+6
(a-2)(a²-4a+1)=a³-2a²-4a²+8a+a-2=a³-6a²+9a-2
(m-3)(m²-2m+4)=m³-3m²-2m²+6m+4m-12=m³-5m²+10m-12
