Question

simplify:(4a+3b+2c)²-(4a+3b-2c)²​

Answer 1

Step-by-step explanation:

Step-by-step explanation:

(4a-3b+2c)²-(4a+3b-2c)²

={(4a-3b+2c)+(4a+3b-2c)}{(4a-3b+2c)-(4a+3b-2c)}

=(4a-3b+2c+4a+3b-2c)(4a-3b+2c-4a-3b+2c)

=8a(4c-6b)

Answer 2

Answer:

32ac + 24bc

Step-by-step explanation:

$x^{2} - y^{2} = (x+y)(x-y)$

x²​ =  (4a+3b+2c)²

y²​ =  (4a+3b-2c)²​

x²​- y²​ = (4a+3b+2c)²-(4a+3b-2c)²​

(x+y) (x-y) = (4a+3b+2c+4a+3b-2c) (4a+3b+2c-4a-3b+2c)

= (8a + 6b) (4c)

= 32ac + 23cb
