do u want factor it ?

Yes

Answer 3

i dont undertand how :P

Answer 4

have you ever studied quadratics ?

Answer 5

Factoring a quadratic trinomial of the form ax^2 + bx + c, a =/= 1
1 Try to factor a common factor out if there is one.
2. Multiply a and c. Find two factors of ac (call them p and q) that add up to b
3. Rewrite the trinomial with the bx term broken up into px + qx, so you have ax^2 + px + qx + c
4. Factor by parts. That means, take a factor out of first two terms and a factor out of last two terms. Then factor out common factor.

Answer 6

21x^2+31x+4
this one can be factored:
you need 2 numbers whose product is +4 and when
these are combined with the factors of 21 add up to 31
7 * 4 = 28
1 * 3 = 3
28 + 3 = 31
and finally, it can be (7x+1)(3x+4)
i hope u can understand above

Answer 7
