Question

Use suitable identities to find the following products.
a) (x+8) (x-10)
a) (3-2x) (3+2x)​

Answer 1

Answer:

That's simple

Step-by-step explanation:

a) (x+8) (x-10)

= x^2-10x+8x-80

=x^2-2x-80=0

=x^2-(8x+10)-80=0

=x-8=0 and x+10=0

Hence x=8 or x=-10

b) (3-2x) (3+2x)

=9+6x-6x+4x^2

=4x^2+9=0

=4x^2=-9

=x^2=-9/4

=x=±-3/2
