Answer:
Therefore values of a and b are

Step-by-step explanation:
Rewrite
in the form
where a and b are integers,
To Find:
a = ?
b = ?
Solution:
..............Given
Which can be written as

Adding half coefficient of X square on both the side we get
...................( 1 )
By identity we have (A - B)² =A² - 2AB + B²
Therefore,

Substituting in equation 1 we get

Which is in the form of

On comparing we get
a = 3 and b = 2
Therefore values of a and b are

Answer:
3s - 10 = 65
Step-by-step explanation:
s = the shirt price
Since Jason bought 3 shirts, we need to multiply the 3 shirts by its value which would be 3s. He has a coupon for $10 off, so we need to subtract 3s by 10. Since he spent $65 we need to set the whole equation equal to 65 and out final answer would be 3s - 10 = 65.
