Question

let us work out 1.5 1)let us write the nature of two roots of the following quadratic equations i) 2x_7x+9=0​

Answer 1

Step-by-step explanation:

nature of roots is given by the equation:

$\sqrt{ {b}^{2} - 4ac}$

Plug in the values of b, a and c

if the answer is

$\sqrt{ {b}^{2} - 4ac} = 0$

roots are real and repeated, if the answer is

$\sqrt{ {b}^{2} - 4ac} < 0$

roots are complex and unequal, if the answer is

$\sqrt{ {b}^{2} - 4ac} > 0$

roots are real and unequal

if

$\sqrt{ {b}^{2} - 4ac} = is \: a \: perfect \: square$

then roots will be rational, other wise irrational

Answer 2

Step-by-step explanation:

this is not a quadratic equation
