solve by long division method x^3- 8x^2+ 6x- 8 ÷ 2x-1
Answers
Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System, being larger than only Mercury. In English, Mars carries the name of the Roman god of war and is often referred to as the "Red Planet".
Answer:
STEP1:Equation at the end of step 1
STEP 2 :
Equation at the end of step2:
STEP3:
4x3 - 8x2 + 3x - 8 Simplify —————————————————— 2x - 1
Checking for a perfect cube :
3.1 4x3 - 8x2 + 3x - 8 is not a perfect cube
Trying to factor by pulling out :
3.2 Factoring: 4x3 - 8x2 + 3x - 8
Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1: 3x - 8
Group 2: -8x2 + 4x3
Pull out from each group separately :
Group 1: (3x - 8) • (1)
Group 2: (x - 2) • (4x2)
Bad news !! Factoring by pulling out fails :
The groups have no common factor and can not be added up to form a multiplication.
