Question

Which of the following is the correct factored form of the given equation?

x 2 + 3x - 4 = 0

Answer 1

It is (x+4)(x-1) because 4 times -1 is -4 and 4-1 is 3.hope this helps

Answer 2

For this case we must factor the following expression:

`x ^ 2 + 3x-4 = 0`

We must find two numbers that when multiplied give as result -4 and when summed give as result +3. These numbers are +4 and -1:

`+ 4-1 = + 3\\4 (-1) = - 4`

Then, the factorization is given by:

`(x + 4) (x-1) = 0`

Answer:

`(x + 4) (x-1) = 0`
