Question

3. Factor the following trinomials: x2 + 10x + 16

Answer 1

\[(x+8)(x+2)\]

Answer 2

(x+2)(x+8)

Answer 3

since 8(2)=16 and 8+2=10

Answer 4

(x+2)(x+8)

Answer 5

\[x^2+10x+16\]
\[x^2+8x+2x+16\]
\[x(x+8) + 2(x+8)\]
this equation is now same as previous one
a(b+c) + d(b+c) = (a+d)(b+c)
therefore
\[(x+2)(x+8)\]
