Secondary SchoolMath 5+3 pts

x²=(7+4√3)²= 7²+4√3²+2×4√3×7

=49+16×3+14×4√3

=97+56√3

rationalize

1/x²=97-(56√3)/97²-56√3²

=97-(56√3)/1

=97-56√3

x²+1/x²= 97+56√3+(97-56√3)

= 97+97

=194

Answer 2

Ello user !!!!!

Here is your answer,

========================

Given=7+4√3

x²=(7+4√3)²= 7²+4√3²+2×4√3×7

=49+16×3+14×4√3

=97+56√3

rationalize

1/x²=97-(56√3)/97²-56√3²

=97-(56√3)/1

=97-56√3

x²+1/x²= 97+56√3+(97-56√3)

= 97+97
