Question

Given that :
a = 3 , b = -1 , c = 2
evaluate:

(3c)² - (-4)²
—————-
. 2(b)(a)

correct answer will be marked as a brainliest answer.

Answer 1

Answer:

Step-by-step explanation:

(3c)^2 -(-4) ^2

---------------------

2(b) (a)

=36-16

-------------

-4

=-5

Answer 2

Here we are given an expression (3c)² - (-4)² / 2(b)(a)

Also, the values of a,b, and c are given

a = 3 , b = -1 , c = 2

We will put these values in the expression

(3c)² - (-4)² / 2(b)(a) = (3 × 2)² - (-4)² / 2(-1)(3)

=( 36 - 8 ) / -6

= 28 / 6

= 4.66

so, the value of given expression will be 4.66
