Question

7. The common root of the quadratic equation x² – 3x + 2 = 0 and 2x² - 5x + 2 = 0 is:
(a) X = 2
(b) x = -2
(c) x=
(d) x = 1
2​

Answer 1

Answer:

a) X = 2

Step-by-step explanation:

if you solve both the quadratic equations by the quadratic formula

which is -b +- root b^2 - 4ac / 2a

then you will get two roots of both the equations and the common one is 2
