Question

(y+1)*(y+3)
(m-1)*(m+4)
(3-5x)*(x+11)
(8-3b)*(b+5)
a(a-3)+(a+1)*(a+4)
Решите пожалуйста
Срочно надо

Answer 1

(y+1)*(y+3)=$y^{2}$+3y+y+3
(m-1)*(m+4)=$m^{2}$+4m-m-4
(3-5x)*(x+11)=3x+33-15$x^{2}$-55
(8-3b)*(b+5)=8b+40-3$b^{2}$-15b
a(a-3)+(a+1)*(a+4)=2$a^{2}$+2a+4

Answer 2

а)(y+1)*(y+3)=+3y+y+3
б)(m-1)*(m+4)=+4m-m-4
в)(3-5x)*(x+11)=3x+33-15-55
г)(8-3b)*(b+5)=8b+40-3-15b
д)a(a-3)+(a+1)*(a+4)=2+2a+4
