Final answer:
To factor and solve the quadratic equation x²+4x-12=0, you can use the factoring method or the quadratic formula. The factored form of the equation is (x-2)(x+6)=0. The solutions for x are x=2 and x=-6.
Step-by-step explanation:
To factor and solve the quadratic equation x²+4x-12=0, we can use the factoring method or the quadratic formula.
which is identical to the second equation when simplified, indicating that the two lines are the same. Select a test point from each interval and substitute it into the inequality to determine if the product is positive or negative in that interval. Therefore, the system does not have a unique solution but rather an infinite number of solutions The factored form of the equation is (x-2)(x+6)=0. To solve for x, we set each factor equal to zero and solve for x, giving us x=2 and x=-6.
