x^2+13x+36=0

Answer 2

$\huge{\boxed{\fcolorbox{cyan}{pink} {Answer}}}$

$~~~~~~~~\sf\boxed{(x + 4) (x + 9)}$

My using the identity we can solve this ;

$\boxed{(x + a)(x + b) = x² + (a + b)x + ab}$

$\sf{ : ⟹ (x)² + (4 + 9)x + (4)(9)}$

$\sf{ : ⟹ (x)² + 13x + 36}$

$\sf{ : ⟹ x² + 13x + 36}$

____________________________

More information ;

$\boxed{(a + b)² = a² + 2ab + b²}$

$\boxed{(a - b)² = a² - 2ab + b²}$

$\boxed{a² – b² = (a + b)(a – b)}$

$\boxed{(x + a)(x + b) = x² + (a + b)x + ab}$
