Explicação passo-a-passo:

y=(-5)^2-4^2+(1-5)-23+1

y=(-5)^2-4^2+(1-5)-23+1 (

(-5)^2

5^2

5×5

25

y=(-5)^2-4^2+(1-5)-23+1

y=25-4^2+(1-5)-23+1

y=(-5)^2-4^2+(1-5)-23+1

4^2

4×4

16

y=(-5)^2-4^2+(1-5)-23+1

y=25-16+(1-5)-23+1

y=(-5)^2-4^2+(1-5)-23+1

1-5

-(5-1)

-4

y=5^2-4^2+(1-5)23+1

y25-16+(-4)-23+1

y=25-16-4-23+1

25-16-4-23+1

26-16--4-23

25-16-4-23+1

26-43

-17

y=25-16-4-23+1
