Question

find of the roots of the equation x²-3x-10=0​

Answer 1

★ Answer :

➝ x² - 3x - 10 = 0

➝ x² - 5x + 2x - 10 = 0

➝ x(x-5) + 2(x-5) = 0

➝ (x-5) (x+2) = 0

➝ x - 5 = 0 ; x + 2 = 0

$\star \: \boxed{\rm x = 5 \: or \: x = - 2}$

Answer 2

★ Answer :-

➝ x² - 3x - 10 = 0

➝ x² - 5x + 2x - 10 = 0

➝ x(x-5) + 2(x-5) = 0

➝ (x-5) (x+2) = 0

➝ x - 5 = 0 ; x + 2 = 0

⋆x=5 or x=-2
