For this case we must factor the following expression:

[tex]x ^ 2 + 3x-4 = 0[/tex]

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:

[tex]+ 4-1 = + 3\\4 (-1) = - 4[/tex]

Then, the factorization is given by:

[tex](x + 4) (x-1) = 0[/tex]

Answer:

[tex](x + 4) (x-1) = 0[/tex]
