Question

Question 2 of 9

Enter the correct answer in the box.
What is the factored form of this expression?
x2 + 6x - 16
Substitute numerical values into the expression for p and q.
(x + p) (x +9)

Answer 1

1.(x-2)(x+8)

Explanation:

1.x2+8x-2x-16

=×(x+8)-2(x+8)

=(x-2)(x+8)

Answer 2

x^2 + 6x - 16

=x^2 + ( 8-2 )x -16

=x^2 + 8x - 2x -16

= X(X+8) -2(X+8). ( Taking common from term 1 and 2 and then from 3 and 4)

= ( X+8 ) ( x-2 ) ( Taking common from term 1 and 2).

so, this is the factored form of the expression x^2 + 6x - 16.
