f(w) = w^2 + 7w + 12
there is no particular answer since it depends on what w is equal to.
normally this type of question is posited as "Solve for w with f(w) = 0?" or
to change its form to (ax + b)(cx + d)
if f(w) = w^2 + 7w + 12
and f(w) = 0
then
0 = w^2 + 7w + 12
simply look at the factors of 12
1 x 12
2 x 6
3 x 4
now consider
(w + a)(w + b) = w^2 + aw + bw + ab
= w^2 + (a+ b)w + ab
since you know
3 x 4 = 12 , and 3 + 4 = 7
this give you
0 = (w + 3) (w + 4) or f(w) = (w + 3)(w + 4)
solving for zero
w = either -3 or -4
as
(-3 + 3)(-3 + 4) = (0)(1) = 0
or
(-4 + 3)(-4 + 4) = (-1)(0) = 0
so depending on what you are actually looking for the answer is
w^2 + 7w +12 = (w + 3)(w + 4)
or
-3 and -4
127w = 847w/7 = 84/7w = 12
3w + 4e + 7w - e3 = 10w - e
7w + 2 = 3w + 94 Subtract 3w from both sides: 4w + 2 = 94 Subtract 2 from both sides: 4w = 92 Divide both sides by 4: w = 23
4y + 3w + 4x + 9y + 7x - 7w (combine like terms)-4w + 11x + 13y
-63=7w
127w = 847w/7 = 84/7w = 12

-36 + 2w = -8w + w -36 + 2w = -7w -36 = -7w - 2w -36 = -9w w = -36/-9 = 4
3w + 4e + 7w - e3 = 10w - e
7w=122 122/7= 17.43 w=17.43

56w2 + 17w - 3 = 56w2 + 24w - 7w - 3 = 8w(7w + 3) - 1(7w + 3) = (7w + 3)(8w - 1)
7w + 2 = 3w + 94 Subtract 3w from both sides: 4w + 2 = 94 Subtract 2 from both sides: 4w = 92 Divide both sides by 4: w = 23
