In a workbook, I gave this answer, but it says it's wrong. Would I get a mark for this in an exam, as it still endus up as x^2 + 3x.

good sufficient element it, what multiples of adverse 4 upload mutually to make effective 3? -4= -1x4 and -a million+4=3 the terrific option? So then you definately harm it down into 2 equations 2(x-a million)(x=4) set each and every equations equivalent to 0 2(x-a million)=0 x=a million and a couple of(x+4)=0 x= -4. There you may desire to have it, in quadratic equations which you've gotten the flexibility to have 2 ideas so your answer is x=a million & -4 i'm hoping this helped : )

Your answer is wrong because you have not simplified it yet...
to simplify, you need to get rid of the zero (since it is not necessary)...
the same would be true if you said (x)(x +1 + 1 +1 +20 -20).. you would need to reduce it down.. it is incomplete as stated.
And, ignore Waheed's answer.

You don't need the zero, although it is correct the way you have it. Leaving it without the zero shows that you know x + 0 = x

ALWAYS LOOK FOR THE GCF FIRST!!!! if there is a GCF. (remember that)
GCF: x
that means you could bring out and x
x(x+3)
you can't factor anymore, so that is your answer.

lol, I guess u neve got mark on it
its X(2X+3), not (X+3)(X+0)

You don't need that zero, otherwise its perfectly good.
