Answer:
√10/2
Step-by-step explanation:
5/√10
Rationalizing the surd involves multiplying the numerator and denominator by the surd.
5/√10 * √10/√10
5√10/10
√10/2
Answer:
Step-by-step explanation:
(x²+4)²-11(x²+4)+24=0
put x²+4=y
y²-11y+24=0
y²-3y-8y+24=0
y(y-3)-8(y-3)=0
(y-3)(y-8)=0
y=3,8
so x²+4=3
x²=-1=i²
x=±i
or x²+4=8
x²=4
x=±2
I think the answer is (-6,30) unless I messed up somewhere
