Consider the following quadratic equation:
9x2+21x=0
Step 1 of 2 : Using the standard form ax2+bx+c=0
of the given quadratic equation, factor the left hand side of the equation into two linear factors.
To factor the left hand side of the equation, we can first factor out the greatest common factor, which is 3x. This gives us:
3x(3x + 7) = 0
We now have a quadratic equation in factored form.
