3x^2 + 2x - 6 if x = -2
=3(-2)^2 + 2(-2) - 6
=12 - 4 - 6
= 2
5x^2 + 6x - 2 if x = -2
=5(-2)^2 + 6(-2) - 2
=20 - 12 - 2
= 6
-2x^3 + 2x^2 if x = 2
= -2(2)^3 + 2(2)^2
= -16 + 8
= -8
Of coz 10.65 is greather because the number after the point was clearly showed it is big number
Answer:

Step-by-step explanation:
2x3 - 5x2 + 4x - 4
Simplify ——————————————————
x - 2
Checking for a perfect cube :
3.1 2x3 - 5x2 + 4x - 4 is not a perfect cube
Trying to factor by pulling out :
3.2 Factoring: 2x3 - 5x2 + 4x - 4
Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1: 4x - 4
Group 2: 2x3 - 5x2
Pull out from each group separately :
Group 1: (x - 1) • (4)
Group 2: (2x - 5) • (x2
