Question

TRY THIS

Verify that I and
3/2
are the roots of the equation 2/2 - 5x+3 = 0.​

Answer 1

Answer:

I got it

Step-by-step explanation:

Let P (x) = 2x 2 - 5x +3

put x=1 in P (x),

P(1)=2(1)2 - 5(1) +3

= 2-5+3=0

P(1) = 0 hence x =1 is the solution /root of 2x 2 -5x +3=0

again, put x = 3/2

P(3/2) = 2(3/2)2 - 5(3/2)2 +3

= 2×9/4 - 15/2 + 3

=9/2 - 15/2 + 6/2

=(9+6)/2-15/2

=15/2 - 15/2 =0

P (3/2) = 0, hence x = 3/2 is the root / solution of 2x 2 -5x +3=0

hope you understand
