Proszę o rozwiązanie pracy domowej z obliczeniami.
1)
=0,5-2*(-3/4)²=0,5-2*9/16=1/2-9/8=4/8-9/8=-5/8
2)
=2a-3a-1+a-5=-6
3)
-3x(5x-2)=-15x²+6x
4)
3a²bc-6ab²c+30abc²=3abc(a-2b+10c
5)
(x-2y)(-3x+5)=-3x²+5x+6xy-10y
6)
(1/2x-2)²=(1/2x)²-2*1/2x*2+2²=*1/4x²-2x+4
7)
=(2x)²-5²=4x²-25
8)
P₀=x²
P₁(x+1)²=x²+2x+1
P₁-P₀=x²+2x+1-x²=2x+1
9)
25/64-9/121a²=(5/8+3/11a)(5/8-3/11a)
10)
=a²+4ab+4b²-4ab+4b²)=a²+4ab+4b²-a²+4ab-4b²=8ab
11)
p*a+q/100*b=pa+qb/100
