Question

Solve by factoring: x2+4x+3=0

Answer 1

\[\large{x^2+4x+3=0}\]
\[\large{x^2+x+3x+3=0}\]
right?

Answer 2

yes

Answer 3

now:
\[\large{x(x+1)+3(x+1)=0}\]
\[\large{(x+3)(x+1)=0}\] right?

Answer 4

now either x+3 = 0 or x + 1 = 0

can you solve these 2 eqn now?

Answer 5

yes, i just subtract 3 and get x=-3 and subtract 1 and get x=-1 , right?

Answer 6

right very right ..

Answer 7

good ..

Answer 8

so the answer is x= -3 &-1

Answer 9

yes
