Question

simplify-2+8x-{5x[2x-(2-7x)+8]-6x}-{5-(4x-7)}​

Answer 1

Answer:

- 45x² - 12x - 14

Step-by-step explanation:

- 2 + 8x - { 5x [ 2x - ( 2 - 7x ) + 8 ] - 6x } - { 5 - ( 4x - 7 ) }​ =

- 2 + 8x - 5x [ 2x - ( 2 - 7x ) + 8 ] + 6x - 5 + ( 4x - 7 ) =

- 2 + 8x - 5x [ 2x - 2 + 7x + 8 ] + 6x - 5 + 4x - 7 =

- 2 + 8x - 10x² + 10x - 35x² - 40x + 6x - 5 + 4x - 7 =

- 45x² - 12x - 14

Answer 2

Step-by-step explanation:

-2+8×-{5×[2×-(-14)+8]-6×}-{5-(-28)}

-2+8×-{5×[2×+14+18]-6×}-{5+28}

-2+8×-{5×[28+18]-6×}-33

-2+8×-{5×46-6×}-33

-2+8×-{230-6×}-33

-2+8×{-224}-33
