Step-by-step explanation:
X⁴-13x²+36
(x²-4)(x²-9)
x²=4. | x²=9
x=√4. |x=√9
x=2. |x=3
27x³-8=0

Answer:
2.28 and 0.22
Step-by-step explanation:
2x²+1=5x
2x²-5x+1=0
this cannot be properly factorized
so let's use the almighty formula,
where a=2, b=-5, c= 1
=-(-5)±√{(-5)²-4x2x1} x 1/(2 x 2)
=5±√25-8 x1/4
=5±√17 x ¼
=(5±4.12)/4
=2.28. or. 0.22
roots=2.28 and 0.22
