The answer for x^2-100 is (x-10)(x+10 .

x^2-100

=x^2-10^2

=x^2-10x+10x-10^2

=(x-10)(x+10).

x^2-100

=x^2-10^2

=x^2-10x+10x-10^2

=(x-10)(x+10).

The answer for x^2+3x+2=0 is x=-1 and x=-2.

x^2+3x+2=0

(x+1)(x+2)=0

x+1=0,x=-1

x+2=0,x=-2.

x^2+3x+2=0

(x+1)(x+2)=0

x+1=0,x=-1

x+2=0,x=-2.

Factor as much as possible: x^2+x-12
**Weegy:** **User:** Factor as much as possible 2x^2+6x+4 **User:** Factor as much as possible: x^2-100 **Weegy:** The answer would be (x+10)(x-10) thus by the FOIL method (First, Outside + Inside, Last) it would be x^2-10x+10x-100, or x^2 - 100.

The factor of x^2+x-12 is (x+4)(x-3).

x^2+x-12

=x^2+4x-3x-12

=(x+4)(x-3).

x^2+x-12

=x^2+4x-3x-12

=(x+4)(x-3).

The answer for 2x^2+6x+4 is 2 (x+1)(+2).

2x^2+6x+4

=2(x^2+3x+2)

=2(x^2+x+2x+2)

=2(x+1)(x+2).

2x^2+6x+4

=2(x^2+3x+2)

=2(x^2+x+2x+2)

=2(x+1)(x+2).

multiply 3x^2.4x^3 **Weegy:** 3x + 2y = 11, y = 4x - > 3x + 2(4x) = 11 - > 3x + 8x = 11 - > x = 11/11 = 1 **User:** multiply 3x^2 . 4x^3 **Weegy:** x=6 and y=-4. Thus x ranges from 0,6,12.... and y ranges from -3,-4,-5.... **User:** divide 3x^9/3x^3 **Weegy:** 9x^4. If you are satisfied with my answer, please click 'Good' on the ratings. Thank you! **User:** divide 3x^9/3x^3
**Weegy:** 9x^4. If you are satisfied with my answer, please click 'Good' on the ratings. Thank you! **User:** Find: (-5x)^2 **Weegy:** The answer is "-125x^3" **User:** Multiply and Simplify: (x + 2)(x + 1) **Weegy:** = x2 + 7x + 10 **User:** Factor out the largest possible common factor (the GCF) from: 15xyz+10xy^2 (More)
