Question

How do you evaluate `b^2+2a-c^2` given a=12, b=9, c=4?

Answer 1

`9^2 + 2(12) - 4^2 = 89`

Explanation:

`a=12, b=9, c=4`

`b^2 +2a - c^2`

`= 9^2 + 2(12) - 4^2`

`= 81 + 24 - 16`

`= 89`

Answer 2

89

Explanation:

`b^2+2a-c^2`
so here `b=9,c=4,a=12(given)`
substituting the values,
`(9)^2+2(12)-(4)^2`
(HOPE YOU NOW`(9)^2=81` AND`(4)^2=16`)
`=81+24-16` `=105-16`
`=89`
SO THE ANSWER HERE IS
`89`
