Question

find the roots of quadratic equation X square - 7 x + 10 is equal to zero

Answer 1

Heya..!!!

_Here Is Your Answer_

____________________________________
X^2 - 7X + 10 = 0
Here we use factorisation method
X^2 - 5X - 2X + 10 = 0
X ( X - 5 ) - 2 ( X - 5 ) = 0
( X - 5 ) ( X - 2 ) = 0
Now ,
X - 5 = 0
X = 5
and,
X - 2 = 0
X = 2
Hence the roots of this equation are 5 and 2

Answer 2

Answer:

5 or 2

Step-by-step explanation:

x² - 7x + 10 = 0

x² - (5+2)x + 10 = 0

x² - 5x - 2x + 10 = 0

x(x - 5) -2(x - 5) = 0

(x - 5) (x - 2) = 0

x = 5 x = 2
