Question

find the following products 1. (x+3)(x-4) 2.(x+4) ( x+6) 3.(a-3) (a-8) 4. ( x-9) ( x+6)​

Answer 1

Answer:

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

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

=x^2-x-12

2.(x+4)(x+6)

x^2+4x+6x+24

=x^2+10x+24

3.(a-3)(a-8)

=a^2-3a-8a+24

=a^2-11a+24

4.(x-9)(x+6)

=x^2-9x+6x-54

=x^2-3x-54

Answer 2

Answer:

$1) {x}^{2} - 12$

$2) {x }^{2} + 10$

$3)a {}^{2} - 24$

$4) {x}^{2} - 54$
