Question

what is the sum of the zeros of the polynomial
$x {}^{2} - 12x + 20$
​

Answer 1

In any quadratic polynomial: The sum of the zeroes is equal to the negative of the coefficient of x by the coefficient of x2. The product of the zeroes is equal to the constant term by the coefficient of x2.

Answer 2

Step-by-step explanation:

• Given polynomial is x²-12x+20
• On comparing with ax²+bx+c then we have
• a=1,b=12 & c=20
• We know that,
• sum of the zeroes= -b/a
• -(-12)/1
• 12
• So , the ans is 12.
