Question

Complete the following activity
I am quadratic equation
My Standard form is ax^2+bx+c=0
My roots are -3-7
Sum of roots =
Product of roots =
Qudratic Equation =​

Answer 1

Explanation:

sum of the roots = alpha + beta = -3--7

product of roots = alpha × beta = -3×-7

quadratic equation =

(alpha + beta)x^2 + (alpha × beta)x+c=0

-10x^2+21x+1=0

Answer 2

Answer:

Sum of roots = -10

Product of roots = 21

Quadratic Equation => x^2 + 10x + 21 = 0

Explanation:

General form of quadratic equation :

x^2 - (sum of roots)x + (product of roots) = 0

x^2 - {-3+(-7)}x + {(-3)×(-7)} = 0

x^2 - (-10)x + 21 = 0

x^2 + 10x + 21 = 0
