Question

Answer it both plzzzz... I need urs help....

Answer 1

this is the correct answer

Answer 2

Hey !!!

polinomial x² -2x +1

that means x² - (@+€)x + @×€

so, here given , @+€ = -b/a = -(-2)/1 = 2

@+ € = 2 ------1)

and @ ×€ = 1 ------2)

then, as we know that a²+b² = (a+b)²-2ab

like that , @²+€²= (@+€)² - 2×@×€

@²+€² = 2²-2×1 {from equation 1 and 2}

@²+€² = 4-2 = 2 answer

*********************************

and , 2} 1/@+1/€ = @+€/@×€

2/1 [from 1 and 2]

2 Answer ...

-----------------------------------
next question
2}

since two zeroes are -1 and -3 ,( x+1)(x+3)

= x²+x +3x +3
= x² +4,x +3

after that Solution is in this pic

your answer is

x + 1 = 0

x = -1 is third zero

Hope it helps you !!!
