Question

1.) Find a polynomial of degree that has zeros 1, -1 and 1/2 and whose leading coefficient is 3.

2.) Find the value of k such that x+3 is a product of P(x) = x^2 - 10kx + 6

Answer 1

My answer for no. 1 is \[3x^3 -( 3x^2/2) - 3x + (3/2)\]
but my teacher said there should be no fractions

Answer 2

then multiply all the terms by 2(the denominator) to get rid of the fraction

Answer 3

but the leading coefficient will not be 3???
