Frank collects souvenirs from places he travels. On a recent trip, he purchased postcards for $2 each and ornaments for $7 each. If he spent a total of $42 on 11 souvenirs, how many ornaments and how many postcards did Frank purchase?

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option
