A laptop is bought for $1380 VAT inclusive. If VAT was charged at 15%, what is the price of the laptop exclusive of VAT?

vat=15%

selling price with vat=$1380

selling price with out vat=?

we have

selling price with vat=$1380

selling price with out vat+vat%of selling price with out vat =$1380

selling price with out vat(1+15/100)=$1380

selling price with out vat=$1380/1.15=$1200

the quotient is 4x^2 - 27x + 167 with a remainder of -996

step-by-step explanation:

in synthetic division, use -6 as the divisor and use the coefficients {4, -3, 5, 6}:

-6     )   4     -3     5     6

                -24   162 -1002

          4   -27   167   -996

thus, the quotient is 4x^2 - 27x + 167 with a remainder of -996.

note:   your "4x°-3x+5x+6" is ambiguous / incomplete.   i had to assume that you meant '4x^3 - 3x^2 + 5x + 6."
