Answer :
Answer:
[tex]a=\sqrt{0.5}[/tex][tex], a=-\sqrt{0.5}[/tex]
Step-by-step explanation:
[tex]a^2+a^2=1[/tex]
[tex]2a^2=1[/tex]
[tex]a^2=0.5[/tex]
[tex]a=\sqrt{0.5}[/tex]
Answer:
a=[tex]\sqrt{\frac{1}{2} }[/tex] , or -[tex]\sqrt{\frac{1}{2} }[/tex].
Step-by-step explanation:
We have 2a^2=1
a^2=1/2
a= plus or minus square root of 1/2.
