\huge\sf\pink{ANSWER:}

1) 1/4 , -1

Given

Alpha + beta =1/4

Alpha ×beta =1

x^2 -(aplha +beta)x + aplha×beta

Putting constant term as K

K(x^2 -(aplha +beta)x + aplha×beta)

Now putting the values

K( x^2-1/4x + (-1)=0

So we get ,

K ( x^2-1/4x -1)=0

Or

By dividing 4 we get

K (4x^2-x-4)=0

Answer:

\huge\bf\underline{\underline{Answer}}

From the formulas of sum and product of zeroes, we know,

Sum of zeroes = α+β

• Product of zeroes = α × β

Sum of zeroes = α+β = \frac{1}{4}

• Product of zeroes = α × β = -1

If α and β are zeroes of any quadratic polynomial, then the quadratic polynomial equation can be written directly as:-

➡ x² –(α+β)x +αβ = 0

➡ x² –(\frac{1}{4} )x +(-1) = 0

➡ 4x² –x-4 = 0

Thus,4x² –x–4 = 0 is the quadratic polynomial.
