Question

3xsquare +5 underroot5x - 10= 0

Answer 1

$\huge{\mathbb{SOLUTION :}}$

===================================
Did you mean :

3x² - 5√5x + 10 = 0

==> 3x² - 3√5x - 2√5x + 10 = 0

==> 3x ( x - √5) - 2√5 ( x - √5) = 0

==> (x - √5) ( 3x - 2√5) = 0

Now,

$\underline{\large{\bold{Case \: I :}}}$

x - √5 = 0

==> x = √5

$\underline{\large{\bold{Case \: II :}}}$

3x - 2√5 = 0

==> 3x = 2√5

==> x = 2√5 / 3
