Use the quadratic formula to solve x2 + 7x + 12 = 0

Question

anonymous · Answer

The quadratic formula states that the solution x is equal to

-b+-(sqrt(b^2-4xaxc))/2a

Where a, b, and c correspond to the coefficients in front of the terms in the quadratic.

In this case (assuming x2 is x^2), 

a=1
b=7
c=12

so the values of x are

-3 and -4

campbell_st · Answer

the gereral form of a quadratic is ax^2 +bx + c = 0

in your question a = 1 b = 7 and c = 12

the general quadratic formula is

$$x = (-b \pm \sqrt{b^2 - 4ac})/2a$$ 

substitute the values and you will find x = -3 and -4
