2x^2+4x+7
Factor to simplest form

Hey bro!

Here the discriminant can't be non-negative. So the factor of this particular quadratic equation won't be real and there is no need to factories it then

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
