x^2 +4x+2x+8
and u have to factor by distributing
for example 4x+6x=2(2x+3x)

if you have to use distribution type., you must group 2 terms with common factors.
x^2 + 4x have x in common and 2x + 8 have 2 in common
factoring out
x(x + 4) + 2 (x + 4)
then they have (x + 4) as a common factor so factor it out
= (x + 4) (x + 2)
you can group different terms, like
x^2 and 2x have x in common and 4x and 8 have 4 in common
factoring out
x (x + 2) + 4 (x + 2)
same process, = (x + 2) (x + 4)., done
you can also add 4x and 2x since they are like terms which gives x^2 + 6x + 8., it would also give you ( x + 4) (x + 2)

First: when you have 4 terms > group "like" terms >>>
(x^2 + 4x) + (2x + 8)
Second: factor each set > find the least common factor >
x(x + 4) + 2(x + 4)
= (x + 4)(x + 2)

x^2 +4x+2x+8 = x^2 + 6x + 8 = (x +4)(x+2)

x² + 4x + 2x + 8
x² + 6x + 8 . . . .Collecting like terms
The question
What two numbres when multiplied gives the product of 8
What two numbers when added gives the sum of 6
The factors are 2 and 4
x² + 6x + 8
(x + 4)(x + 2) = x² + 4x + 2x + 8 = x² + 6x + 8

x^2 +4x+2x+8
= x(x+4) + 2(x+4)
= (x+2)(x+4)

x^2 +4x+2x+8
x^2+6x+8
(x+4)(x+2)
4x+6x=2(2x+3x)
10x=2*5x=10x
10x=10x always true for all values of x

x(x+4)+2(x+4)
=(x+2)(x+4)

the respond is (x -11)(x-3). First you positioned x interior the 1st area of each and every set of parenthesis considering which you desire to finally finally end up with x^2. then you certainly locate aspects of 33 that upload as much as -14: those aspects are -11 and -3. you positioned those interior the 2nd area of each and every set of parenthesis. you could examine your answer via multiplying (x-11) situations (x-3) and you ought to finally finally end up with x^2 - 14x + 33.

it's just x^2+6x+8, which is x=-2 and x=-4
if you haven't learned that. it's (x+2)(x+4)

if carrying on doing is...X^2+6x+8...then becomes (X+4)(X+2)
