Nature of roots |

1 |
b^{2} -4ac > 0 |
Two distinct real roots |

2 |
b^{2}-4ac =0 |
One real root |

3 |
b^{2}-4ac < 0 |
No real roots |

No real roots : (a) ,(c),(h)

a) x

b) x

a)

x

x(x-5) +2(x-5)=0

(x+2)(x-5)=0

So roots are x=-2 and 5

b) Roots are 5 and 6

a) x

b) 2x

Solution

a)

(x+4/2)

(x+2)

(x+2)

x+2=±3

x=1 or -5

b)

(x-7/4)

(x-7/4)

(x-7/4)

x-7/4=±5/4

or

x=1/2 or 3

a) There are no reals roots of the quadratic equation x

b) The roots of the equation x

c) A quadratic equation can have at most 2 real roots

d) In a quadratic equation ax

e) In a quadratic equation ax

f) for k > 0,the quadratic equation 2x

g) if the roots of the quadratic equation are rational, the coefficient of the term x will also be rational.

h) if the roots of the quadratic equation are irrational, the coefficient of the term x will also be irrational

I) Every quadratic equation will have rational roots

- True
- True

a) 21

b) 13

c)11

d) 12

x

x

x= 12 or -9

So answer is 12

x

a) (4,10)

b) (-4,10)

c) (-4,-10)

d) (4,-10)

x

a) is a quadratic equation

b) is not a quadratic equation

x

a) are real

b) are not real
