Solve the equation using the quadratic formula
2x^2=8x+3
the solution sets are

(-0.35, 4.35)  to the nearest hundredth.

Step-by-step explanation:

2x^2=8x+3

2x^2 - 8x - 3 = 0

The formula for the solution of ax^2 + bx + c = 0 is:

x = [-b +/- sqrt(b^2 - 4ac)] / 2a.

Here x = [-(-8) +/- sqrt((-8)^2 - 4*2*-3)] / 4

= (8 +/- sqrt(88))/ 4

= 2 +/- sqrt88/4

= -0.35, 4.35.

answer: $34.31

step-by-step explanation:

$11.99 x 3 = $35.97

$35.97 - 10% = $32.37

$32.37 + 6% = $34.31
