Q. Find all real solutions to the equation:x5−5x4+10x3−10x2+5x−1=0
Pattern Recognition: Notice the pattern in the coefficients, it looks like the binomial theorem expansion of (x−1)5. Let's check if (x−1)5 equals the given polynomial. (x−1)5=x5−5x4+10x3−10x2+5x−1 Yep, it matches exactly.
Equation Simplification: Since (x−1)5 equals the given polynomial, we can write the equation as:(x−1)5=0
Finding Real Solutions: To find the real solutions, we need to solve for x in the equation (x−1)5=0. Taking the fifth root of both sides gives us x−1=0.
Final Solution: Now, solve for x by adding 1 to both sides.x=1
