Question

factorize by using algebraic identities x^2+4x+3

Answer 1

Answer:

${x}^{2} + 4x + 3 = 0$

${x}^{2} + x + 3x + 3 = 0$

$x(x + 1) + 3(x + 1) = 0$

$= > (x + 1)(x + 3) = 0$

$= > x = - 1 \: or \: x = - 3$

Answer 2

The correct answer is "x = -2" or "x = -3".

Step-by-step explanation:

$The \ given \ equation \ is:\\\\x^2+4x+3\\\\On \ factorizing \ the \ above \ equation,we \ get\\\\x^2+3x+x+3=0\\\\x(x+3)+2(x+3)=0\\\\(x+2)(x+3)=0\\\\x+2=0\\\\x=-2\\\\Or,\\\\x+3=0\\\\x=-3$
