(5x^4-9x^3+7x-1)+(-8x^4+4x^2-3x+2)- (4x^3+5x-1)(2x-7) what is the simplified version of this polynomial expression

Write the component forms of vectors u and v, shown in the graph, and find v − 2u. u= (< -3, -2> , < -3, -1> , < -2, -2> , < -2, -1> ) v= (< -5, 1> , -4, 0> , < 0, -4> , < 1, -5> ) v-2u= (< 5, 3> , < 0, 4> , < 4, 0> , < 5, -3>
