Question

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

Answer 1

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

Answer 2

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

Answer 3

x = -3 and x= -4

Answer 4

ty all for the help
