Using P.E.M.D.A.S.
Parentheses, Exponent, Multiplication, Division, Addition, Subtraction.
You would start at (5.8 - 7.09) which equals (-1.29).
Then you would do 3.5 x (-1.29) which equals -4.515
Hope this helps.

:
((23x3 - (2•7x2)) - 11x) + 3

:
Checking for a perfect cube
3.1 8x3-14x2-11x+3 is not a perfect cube
Trying to factor by pulling out :
3.2 Factoring: 8x3-14x2-11x+3
Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1: -11x+3
Group 2: 8x3-14x2
Pull out from each group separately :
Group 1: (-11x+3) • (1) = (11x-3) • (-1)
Group 2: (4x-7) • (2x2)
