What are the solutions to x^2 + 4x - 12 = 0?

That can be factored:

(x +6) * (x -2)

Therefore, x = -6 and x =2

Step-by-step explanation:

For this case we have the following quadratic equation:

We can factor the equation, for it, we must find two numbers that when multiplied give as result -12 and when summed give as result +4. These numbers are: +6 and -2.

Then, the factorization is given by:

Thus, the solutions are:

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.

range =5

step-by-step explanation:

to find the range, we take the largest value and subtract the smallest value.

the largest value is 5

the smallest value is 0

the range is 5-0   =5
