Answer»

ANSWER:

4√6

Step-by-step explanation:

Radii 4 cm and 6 cm.

AB =6+4=10 cm

∠Y=90deg

then ,

BF=6−4=2cm

In △BYA

AY2 =AB2-BY2

=10 ^2 -2^2

AY= √100−4

AY= √96

AY=4 √6

AY∣∣CD

Hence,

CD=4 √6

Determine the nature of the roots for the quadratsequotion.3x+2x-2=0​

Answer»

\large\underline{\bold{Given \:Question - }}

\sf \: Determine  \: the \:  nature  \: of \:  the \:  <klux>ROOTS</klux> \:  for \:  the \: quadratic \: equation :

\sf \:  {3x}^{2}  + 2x - 2 = 0

\large\underline{\bold{Solution-}}

Concept Used :-

Nature of roots :-

Let us consider a quadratic equation ax² + bx + c = 0, then nature of roots of quadratic equation depends upon Discriminant (D) of the quadratic equation.

  • If Discriminant, D > 0, then roots of the equation are real and unequal.

  • If Discriminant, D = 0, then roots of the equation are real and equal.

  • If Discriminant, D < 0, then roots of the equation are unreal or complex or imaginary.

Where,

  • Discriminant, D = b² - 4ac

Here,

The given quadratic equation is

\sf \:  {3x}^{2}  + 2x - 2 = 0

On comparing with ax² + bx + c = 0, we get

\:  \:  \:  \:  \:  \:  \:  \:  \bull \: \sf \: a \:  =  \: 3

\:  \:  \:  \:  \:  \:  \:  \:  \bull \: \sf \: b \:  =  \: 2

\:  \:  \:  \:  \:  \:  \:  \:  \bull \: \sf \: c \:  =  \:  -  \: 2

Now,

Discriminant, of quadratic equation is given by

\bf \: Discriminant, D \:  =  \sf \:  {b}^{2}  - 4ac

On substituting the values of a, b and c, we get

\bf \: Discriminant, D \:  = \sf \:  {(2)}^{2}  - 4 \times (3) \times ( - 2)

\bf \: Discriminant, D \:  = \sf \: 4 + 24

\bf \: Discriminant, D \:  = \sf \: 28

\rm :\implies\:\bf \: Discriminant, D \:   >  \: 0

\bf \: Hence,  \: equation  \: has \:  real \:  and  \: distinct  \: roots.

ADDITIONAL Information :-

A quadratic equation is an equation of degree 2, mean that the highest exponent of this equation is 2. Moreover, the STANDARD quadratic equation is ax² + bx + c, where a, b, and c are real numbers or arbitrary constants and ‘a’ cannot be 0. An example of quadratic equation is 2x² + 5x + 4.

The quadratic expression can also be written as:

  • Standard FORM: y = ax² + bx + c, here a, b, and c are real numbers.

  • Factored Form: y = (AX + c) (bx + d) here also a, b, and c are real numbers.

  • Vertex Form: y = a (x + b)² + c, and here also a, b, and c are real numbers.
