(2a + 5)²

(5x + y)²

(4a + 3b)²

(x – 6)²

(3a – 4)²

(3x – y)²

Answer 1

Explicação passo-a-passo:

(x + 3)² =(x+3).(x+3)

(x+3)²=(x)²+2.(x).(3)+(3)²

(x+3)²=x²+6x+9

(2a + 5)² =(2a+5).(2a+5)

(2a+5)=(2a)²-2.(2a).(5)+(5)²

(2a+5)=4a²-20a+25

(5x + y)² =(5x+y).(5x+y)

(5x+y)²=(5x)²+2.(5x).(y)+(y)²

(5x+y)²=25x²+10xy+y²

(4a + 3b)²=(4a+3b).(4a+3b)

(4a+3b)²=(4a)²+2.(4a).(3b)+(3b)²

(4a+3b)²= 16a²+24ab+9b²

(x -6)² =(x-6).(x-6)

(x- 6)²=(x)²+2.(x).(-6)+(-6)²

(x-6)²=x²-12x +36

(3a-4)² =(3a-4).(3a-4)

(3a-4)²=(3a)²+2.(3a).(-4)+(-4)²

(3a-4)²=9a²-24a+16

(3x-y)²=(3x-y).(3x-y)

(3x-y)²=(3x)²+2.(3x).(-y)+(-y)²

(3x-y)²=9x²-6xy+y²
