Question

write the quadratic equation if the sum of roots is 20 and product of the root is 25​

Answer 1

Given,

Sum of roots = 20

Product of roots = 25

To find,

Formation of a quadratic equation from the given substances.

Solution,

We can easily solve this mathematical problem by the following process.

A quadratic equation can be derived from it's roots by the following mathematical formula :

quadratic equation :

x²- (sum of roots)x + (product of roots) = 0

x² - (20)x + 25 = 0 [By putting values.]

x²-20x+25 = 0

Hence, the quadratic equation is x²-20x+25 = 0
