Question

Juanita begins to factor an expression as shown.

x2+3x−18=(x+)(x−)

What numbers should be placed in the boxes from left to right?

Answer 1

(x+6)(x-3)

solve:

`\sf x^2+3x-18`

the least common multiple of 1 and 18 is 18 : 6 * 3

`\sf x^2+6x-3x-18`

breakdown

`\sf x(x+6)-3(x+6)`

build parenthesis

`\sf (x-3)(x+6)`
