Question

Please help! Just show all of the steps and explain it to me please. and yes i did try to do this myself too

Answer 1

use order of operations or PEMDAS

this is order of simplification

work from left to right
Parentahsees (grouping symbols)
Exponents
multiplication or division
addition or subtraction


so
replace a with 1, b=2 and c with -8


`-2(3(1)-6)^2+5(-8) / 4*(-3)-(-2(2))^3`

`-2(3-6)^2+5(-8) / 4*(-3))-(-2(2))^3`

`-2(-3)^2+5(-8) / 4*(-3)-(-2(2))^3`

`-2(-3)^2+5(-8) / 4*(-3)-(-4)^3`
now exponents

`-2(9)+5(-8) / 4*-3)-(-4)^3`

`-2(9)+5(-8) / 4*(-3)-(-64)`
multiply and divide, working from left to right (remember, division is multiplication by a fraction)

`-18+5(-8) / 4*(-3)-(-64)`

`-18-40 / 4*(-3)-(-64)`

`-18-10*(-3)-(-64)`

`-18+30-(-64)`

`-18+30-1(-64)`

`-18+30+64`
addition and subtraction

`12+64`

`76`
