Question

solve the following quadratic equation by factoring:
1.) x^2+2x=o
2.) 2x^2=6x
3.) 2a^2+a =o
4.) 6m^2+9m=o
5.) b^2=1

Answer 1

i'll solve one as an example since they are all the same
1.
\(x^2+2x=0\)
take out common factor
\(x(x+2)=0\)
use Null factor law
\(x = 0\) or \(x+2 = 0\)
\(x = -2\) or \(x = 0\)

Answer 2

thanks
but can you solve also the number 2.

Answer 3

it's the same, just move them to one side of the equation and factorise

Answer 4

ahh
ok.
thanks again
