Question

Form the polynomial whose zeroes are 2 + 1 /√2 , 2 − 1/√2 .
Please answer correctly ​

Answer 1

HEY MATE HERE'S YOUR ANSWER________

GIVEN:-

→α=2+1√2

→β=2-1√2

\rule{200}{1}

TO FIND:-

→ A Polynomial using Quadratic Formula?

\rule{200}{1}

ANSWER:::---

•Using Quadratic Formula•

๛k[x²-(α+β)x+αβ]–(1)

→α+β=2+1√2+(2-1√2)

→α+β=4–(2)

→αβ=(2+1√2)×(2-1√2)

→αβ=4-2√2+2√2-2

→αβ=2–(3)

★Using (3)&(2) in (1)★

→k[x²-(4)x+2]

→k[x²-4x+2]

♦Let k=1♦

→1[x²-4x+2]

→x²-4x+2

๛x²-4x+2 is the Polynomial๛

\rule{200}{2}
