Question

Find the roots by factorization method:2x to the power of 2 -5x+3=0
plz slove this

Answer 1

AnsWer :

x = 3 and - 1 / 2.

Correct QuestioN :

Find the roots by factorization method : 2x² - 5x - 3 = 0.

SolutioN :

Factorization method :

→ 2x² - 5x - 3 = 0.

→ 2x² - 6x + x - 3 = 0.

→ 2x( x - 3 ) + 1( x - 3 ) = 0.

→ ( 2x + 1 )( x - 3 ) = 0.

▂▂▂▂▂▂▂▂

 Either,

→ 2x + 1 = 0.

→ 2x = - 1.

→ x = - 1 / 2.

▂▂▂▂▂▂▂▂

  Or,

→ x - 3 = 0.

→ x = 3.

Therefore, the value of x is 3 and - 1 / 2.

Answer 2

x = 3 and - 1 / 2.

Correct QuestioN :

Find the roots by factorization method : 2x² - 5x - 3 = 0.

→ 2x = - 1.

→ x = - 1 / 2.
