Question

1-Desenvolva:
$(x - a) {}^{2} =$
$(x - 10) {}^{2} =$
$(3x - 1) {}^{2} =$
$(5a - 3b) {}^{2} =$
$(a {}^{2} - 4) {}^{2} =$
$(x {}^{2} - 1) =$
$(2b - 1) {}^{2} =$
$(3x - 1) {}^{2} =$
$(3ab - 1) {}^{2} =$
$(x {}^{2} - y {}^{2} ) {}^{2} =$
Alguém me ajuda?
Por favor

Answer 1

(x-a)²--x²-2ax +a²

(x-10)²--x²-2x.10+10°²--x²-20x+100

(3x-1)²--(3x)²-2.3x.1+1²---9x²-6x+1

(5a-3b)²--(5a)²-2.5a.3b+(3b)²--25a²-30ab+9b²

(a²-4)²--(a²)²-2a².4+4²--a4-8a²+16

(x²-1)--(x-1)(x+1)

(2b-1)²--(2b)²-2.2b.1+1²--4b²-4b+1

(3ab-1)²---(3ab)²-2.3ab.1+1²--9a²b²-6ab+1

(x²-y²)²--(x²)²-2x²y²+(y²)²--x4-2x²y²+y4
