Question

Determine the value of the root of the following quadratic equation from their discriminant x² -2x+ 9/4 = 0​

Answer 1

➲CORRECT QUESTION :-

Determine the value of the root of the following quadratic equation from their discriminant $\sf{x^2 -2x+\dfrac{9}{4}= 0}$

❂ GIVEN :

$\sf{x^2 -2x+\dfrac{9}{4} = 0}$ .

❂ TO FIND :

The value of the root.

➲SOLUTION :-

⦿ We have,

a = 1

b = -2

c = 9/4

✞ FORMULA REQUIRED :

$\boxed {\red{\bf{D= b^2 - 4ac}}}$

$\boxed{\pink{\bf{Roots= \dfrac{ - b \pm \sqrt{D} }{2a}}}}$

Substituting the values in first formula :

$: \implies \sf{D= b^2 - 4ac}$

$: \implies \sf{D= ( - 2)^2 - \cancel{4}\times 1\times \dfrac{9}{\cancel{4}} }$

$: \implies \sf{D= 4 - 9}$

$: \implies \underline{\underline{\tt{D= -5}}}$
