Answer 1

Step-by-step explanation:

Question :-

➡ Determine the value of the root of the following quadratic equation from their discriminant =

$→\ \bold{ {x}^{2} - 2x + \frac{9}{4} = 0}$

________________________________

Given :-

$→\ \bold \red{ {x}^{2} - 2x + \frac{9}{4} = 0}$

________________________________

To Find :-

• The value of the Root.

________________________________

Solution :-

➡ We have,

• a = 1
• b = -2
• c = 9/4

________________________________

Formula Required :-

$➡ \: \large \bold \pink{D = {b}^{2} - 4ac }$

________________________________

Now,

• Substituting the values in the first formula, we will get :-

$➡ \: \ \bold\blue{D = {b}^{2} - 4ac } \\ \\ ➡\ \bold\blue{ \:D \: = ( { - 2})^{2} - 4 \times 1 \times \frac{9}{4} } \\ \\\large{\bold{\fcolorbox{black}{red}{D = -5}}}$

________________________________

Here,

➡ D < 0

• So, the roots are not real & are unequal.

Answer 2

The value of the root.

a = 1

b = -2

c = 9/4

Substituting the values in first formula :

$D=b^{2} -4ac\\D=(-2)^{2} -4*1*\frac{9}{4} \\D=4-9\\D=-5$
