Question

Evaluate each equation as if a= 2, b=(3)/(2) and C=3

a^(2)-(ab+c)

Please show steps.

Answer 1

`\large \bf \implies{4}`

Explanation:

Given :

• 
  `\bf{a = 2}`
• 
  `\bf{b = (3)/(2) }`
• 
  `\bf{c = 3}`

To Find :

Evaluate it
`\Downarrow`

`\bf \longrightarrow {a}^(2) - (ab + c)`

Solution :

`\bf \longrightarrow{a}^(2) - (ab + c)`

Putting the values according to the question:

`\bf \longrightarrow {(2)}^(2) - ((2)( (3)/(2) ) + (3)) \\ \\ \bf \longrightarrow4 - \cancel{2} * \frac{3}{ \cancel{2}} + 3 \\ \\\bf \longrightarrow 4 - \cancel{ 3 + 3} \\ \\ \bf \longrightarrow4`
