Find a quadratic polynomial with the given numbers as the sum and product of it zeroes ⅔, -4

Step-by-step explanation:

sum=2/3 and product=-4

x^2-(sum)x+(product)

x^2-2/3x+(-4)

x^2-2/3x-4

1/3(3x^2-2x-12)

the polynomial is 3x^2-2x-12

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
