(x+1)(x+4)=14
is this correct:
x - 1 = 14 or x + 4 = 14
+1 +1 - 4 - 4
x = 15 x = 10

Question

(x+1)(x+4)=14 
is this correct:

I got,  x=13
          x=10

anonymous · Answer

you do the opposite of what is in parenthesis

anonymous · Answer

In the first parenthesis you have (x+1) but transfered it x-1 when solving.  Is this correct?

anonymous · Answer

(x+1)(x+4)=14
x+1=14,  x+4+14
   -1  -1      -4  -4
x=13          x=10

anonymous · Answer

so mistake in adding 1 instead of subracting. thx!

anonymous · Answer

Unfortunately that is not correct at all =/  it is not true that:$$(x+1)(x+4)=14\Longrightarrow x+1=14,x+4=14$$You will have to multiply out the (x+1)(x+4) first, then subtract 14 from both sides, then solve the problem.

$$x^2+x+4x+4=14 => x^2+5x+4-14=0$$

myininaya · Answer

$$x^2+5x-10=0$$
