Question

Simplify:
(3x + 4) ^2 - (3x-4)^2​

Answer 1

Answer:

48x

Step-by-step explanation:

here we can use the identity that $(a+b)^{2} = a^{2} + 2ab + b^{2}$

and $(a-b)^{2}=a^{2}-2ab+b^{2}$

$(3x+4)^{2}-(3x-4)^{2} =(9x^{2} +24x+16) - (9x^{2} -24x+16)$

$=9x^{2} +24x+16-9x^{2} +24b-16$

$=48x$
