Question

Efetue

1-(5x²-2x+3-(3x²-7x+5)

2-(13x²+8x-10)-(10x²+2x-7)

Answer 1

Resposta correta abaixo:
1- (5x²-2x+3)-(3x²-7x+5) = 0,35083008
2- (13x²+8x-10)-(10x²+2x-7) = 0,41418457

Answer 2

1)
= (5x²-2x+3) -(3x²-7x+5)
= 5x^2 -3x^2 -2x +7x+3 - 5
= 2x^2+ 5x - 2

2)
= (13x²+8x-10)-(10x²+2x-7)
= 13x^2 - 10x^2 +8x - 2x -10 + 7
= 3x^2 +6x - 3
