Question

solve the equation x²-7x+12=0​

Answer 1

Step-by-step explanation:

here we using formula ax^+bx+c=0 therefore a=x^,b=-7 ,c=12..

Answer 2

$\Huge\rm\color{red}{answer:}$

$\sf{ }$

$\bf{{\underline{To~solve}}:}$

$\sf{~~~~~~~~~~~ x^{2}-7x+12=0}$

$\bf{Here,~~S=-7~~~P=12~~~~(-3,-4)}$

$\sf{:\implies (x^{2}-4x)+(-3x+12)=0}$

$\sf{:\implies [x(x-4)~]+[-3(x-4)~]=0}$

$\sf{:\implies (x-3)(x-4)=0}$

$\sf{:\implies x-3=0~~~~~~or~~~~~~x-4=0}$

$\sf{:\implies {\color{red}{\boxed{\bf{x=3}}}}~~~~~~or~~~~~~{\color{red}{\boxed{\bf{x=4}}}}}$
