Question

2. If x = 0 and y = 3, evaluate: (a) 8x2 – 7xy +3 ​

Answer 1

Answer:

3

Step-by-step explanation:

8x² -7xy +3

put value of x=0 and y=3 in above equation

= 8(0)² -7×0×3 +3

= 0 -0 +3

= 3

Answer 2

Answer:

The value of $8x^{2} -7xy+3$ at $x=0, y=3$ is $3$.

Step-by-step explanation:

Given : The expression is $8x^{2} -7xy+3$

To find : The value of expression if $x=0, y=3$.

Solution :

• The given quadratic equation is,

       $8x^{2} -7xy+3$

• We have to find the value of expression if $x=0, y=3$.
• To find the value, put $x=0, y=3$ in given expression.
• So, the given expression is,

      $8x^{2} -7xy+3$

• Putting $x=0, y=3$ in given expression, we get

     $8x^{2} -7xy+3$ $= 8(0)^{2} -7*0*3+3$

                        $=0-0+3$

                        = $3$

• ∴ The value of $8x^{2} -7xy+3$ at $x=0, y=3$ is $3$.
