Answer:
−3.691743,2.199107
Step-by-step explanation:
x(x+1)²(x+2)=72
x⁴+ 3x³+ 3x²+ x= 72
Step 1: Subtract 72 from both sides.
x⁴+ 3x³+ 3x²+ x - 72= 72-72
x⁴+ 3x³+ 3x²+ x - 72= 0
Step 2: Use quartic formula.
x= −3.691743,2.199107

what after x⁴+3x³+3x²+x-72=0 ??
use quartic formula
how you can use quadratic formula when the highest power is 4 ?
Quartic formula is a function of the form f(x)=ax⁴+bx³+cx²+dx+e, where a is nonzero, which is defined by a polynomial of degree four, called a quartic polynomial.
