Question

Juanita begins to factor an expression as shown. x2 + 3x – 18 = (x + )(x – ) The numbers that should be placed in the boxes, from left to right

Answer 1

6 and 3 is your answer.

Answer 2

From left to right missing numbers are 6 and 3.

Explanation:

Given expression is x² + 3x - 18

After factorization Juanita write ( x + _ ) ( x - _ )

We have to find missing value.

First we factorize the given expression using middle term split method,

Consider,

x² + 3x - 18

= x² + 6x - 3x - 18

= x ( x + 6 ) - 3 ( x + 6 )

= ( x + 6 ) ( x - 3 )

Therefore, From left to right missing numbers are 6 and 3.
