Answer:
x^2-3x-28
Multiply the coefficents of the first and last terms, and find two factors that add to the coefficent of the middle term.
x^2-7x+4x-28=x(x-7)+4(x-7)
(x+4)(x-7)
Here, Original price = $14.50
Discount = 30%
Now, Amount of discount = 14.50*0.30 = $4.35
So, price after discount would be: $14.50 - $4.35 = $10.15
Your answer is $10.15
Hope this helps!
