Find nature of root 3x2-√3+4=0​

Answer»

Answer:

For a quadratic EQUATION ax² + bx + c =0, the TERM b² - 4ac is called discriminant (D) of the quadratic equation because it  determines  whether the quadratic equation has real roots or not ( nature of roots).

D=  b² - 4ac

So a quadratic equation ax² + bx + c =0, has

i) Two distinct real roots, if b² - 4ac >0 , then x= -b/2a + √D/2a  &x= -b/2a - √D/2a

ii) Two EQUAL real roots, if b² - 4ac = 0 , then x= -b/2a or -b/2a

iii) No real roots, if b² - 4ac <0

SOLUTION:

Given: 3x² – 4√3x + 4 = 0

On Comparing it with ax² + bx + c = 0, we get

a = 3, b = -4√3 and c = 4

Discriminant(D) = b² – 4ac

D= (-4√3)² – 4(3)(4)

D= 16 × 3 - 48

48 – 48 = 0

As , b² – 4ac = 0,

Hence,the given quadratic equation has  real and equal roots.

HOPE THIS WILL HELP YOU  ^_^

22.

The diagonal of a square is 10cm. find its area.​

Answer»

ANSWER:

DIAGONAL = SIDE √2

side = x

10 = x√2

x = 10/√2

by rationalising

10/√2 ×√2/√2 = 10√2/2

= 5√2

side = 5√2 cm

area = side ×side

= 5√2×5√2

= 25×2

= 50cm^2.

In the given figure,angleCAB =40°, AC=AB and BC =BD. Find:¡] angleACB ¡¡]angleCDB ​

Answer»

Answer:

AC = AB

SO angleACB and angle CBA are equal

let them to be x

angle CAB+ACB+CBA=180( ANGLE SUM PROPERTY)

40 +X+X=180

40+2X=180

2X=180-40

×=140/2

X=70

i.e ACB=70

CBA + CBD=180(linear PAIR)

70+y = 180

y=110

CDB= 110

BC=BD

so angle BCD AND BDC are equal

let them be k

CDB+BCD+BDC=180

110 +K+K=180

2K=70

K=35

THIS MEANS BCD = 35
