Answer:
The real roots are
and
The sum of the squares of these roots is
Step-by-step explanation:
The given quadratic equation is has two real roots.
To find the roots .
Dividing the above equation by 2
For quadratic equation the solution is
Where a and b are coefficents of and x respectively, c is a constant.
For given quadratic equation
a=4, b=6, c=-7
The real roots are
and
Now to find the sum of the squares of these roots
Therefore the sum of the squares of these roots is
The correct question in the attached figure
case A) an=2<span>^(n-1)
for n=8
a8=2</span>^(8-1)-----> a8=2<span>^7----> a8=128
the answer case A) is
a8=128
case B) an=7
then for n=8
a8=7
the answer case B) is
a8=7
case C) an=1+(-1)</span><span>^n
for n=8
a8=1+(-1)</span><span>^8----> a8=1+1----> a8=2
the answer case C) is
a8=2
case D)an=-(-2)</span><span>^n
for n=8
a8=-(-2)</span><span>^8----> a8=-256
the answer case D) is
a8=-256</span>
