Solution

Given :-

  • Zeroes of Quadratic Equation is , 2 & 1/2

Find :-

  • Quadratic equations

Explanation

Let

  • p & q be zeroes of this Equation

Then,

==> Sum of zeroes (p + q) = 2 + 1/2 =(4+1)/2

==> Sum of zeroes (p + q) = 5/2

and,

==> Product of zeroes (p.q) = 2 . 1/2

==> product of zeros (p.q) = 1

Formula Of Quadratic Equation

\dag\boxed{\underline{\tt{\red{\:x^2-(p+q)x+(p.q)=0}}}}

Keep all above Values

==> x² - (5/2)x + 1 = 0

==> (2x² - 5x + 2 )/2 = 0

==> 2x² - 5x + 2 = 0

Hence

  • Quadratic equations will be (2x² - 5x + 2 = 0)

Given:-

  • α = 2
  • ß = \sf\dfrac{1}{2}

To find:-

  • the quadratic equation

Formula:-

:\implies\underline\pink{\boxed{\bf p(x) = x²-(α+ß)x+αß}}

Solution:-

  • α+ß = \sf 2+\dfrac{1}{2}=\dfrac{5}{2}
  • αß = \sf\dfrac{1}{2}×2=1

:\impliesp(x) = \sf x²-\dfrac{5}{2}x+1

now, let's multiply the entire equation with 2 so that the denominator gets removed

:\impliesp(x) = \sf 2x²-5x+2
