30² -5x+2=0 rusi
using
the
quadratic formule
​

Answer 1

Answer:

$\huge\red{\underline{\mathbb{Explanation:-}}}$

The given equation is:-

= 30^2- 5x + 2=0

Now, we compare the given equation is ax^2+bx+c

so, we get:-

a= 30

b=-5

and, c= 2

using formula:-

Discriminant ,D= b^2-4ac

put the values in above formula

=(-5)^2-4*30*2

=25-240

d=-215

Now,

we know that:-

x= b +-√b^2-4ac/2a

x= 5 +(-215)/60

x=5-215/60

x=210/60

x=+7/2 or -7/2.

so, the roots of given equation is +7/2 or -7/2
