Answer 1

$\huge\sf\underline{ \rm {question \: }}$

3x² - 5x + 12 = 0

$\huge\sf\underline{ \rm \blue{answer \: }}$

4 and 1

$\sf\underline{ \rm \red{step \: by \: step \: explanation \: = }}$

⠀⠀⠀⠀⠀⠀

By using split middle term method,

⠀⠀⠀⠀⠀⠀

⟹ 3x² - 12x - 3x + 12 = 0

⠀⠀⠀⠀⠀⠀

⟹ 3x(x-4) - 3 (x-4) = 0

⠀⠀⠀⠀⠀⠀

⟹ (x-4) (3x-3) = 0

⠀⠀⠀⠀⠀⠀

⟹ (x-4) = 0 and (3x-3) = 0

⠀⠀⠀⠀⠀⠀

⟹ x = 4 and x = 1

⠀⠀⠀⠀⠀⠀

Therefore, roots of given

 equation are : 4 and 1.
