Question

Efetue as operações (Matemática)

Answer 1

Explicação passo-a-passo:

a) (3x-4)×(2ײ-5×+1)

3(2ײ-5×+1)-4(2ײ-5×+1)

6׳15ײ+3×-8ײ+20×-4

6׳-15ײ+3×-8ײ+20×-4

6׳-23ײ+23×-4

b) (y-6y+1)×(2y²-3y+5)

y²(2y²-3y+5)-6y(2y²-3y+5)+1(2y-3y+5)

2y⁴-3y³+5y²-12y³+18y²-30y+2y²-3y+5

2y⁴-15y³+25y²-33y+5

c) (×-1)-(ײ+7×+10)

x-1-x²+7x-10

8x-11-x²

-x²+8x-11

d) (3x²+2x-5)+(3x+11)

3x²+2x-5+3x+11

3x²+5x+6

e) (5x²+4x-2)-(2x³-x²-2x-5)

5x³+4x-2-2x³+x²+2x+5

3x³+6x+3+x²

3x³+x²6x+3

f) (x³+2x)-(x+4)

x³+2x-x-4

x³+x-4
