Answer: x = -1
x =(5-√17)/2= 0.438
x =(5+√17)/2= 4.562
Step by step solution :
Step 1 :
Equation at the end of step 1 :
(((x3) - 22x2) - 3x) + 2 = 0
Step 2 :
Checking for a perfect cube :
2.1 x3-4x2-3x+2 is not a perfect cube
Trying to factor by pulling out :
2.2 Factoring: x3-4x2-3x+2
Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1: -3x+2
Group 2: x3-4x2
Pull out from each group separately :
Group 1: (-3x+2) • (1) = (3x-2) • (-1)
Group 2: (x-4) • (x2)
