Question:
Solve the equation 2x2−5x+3=0 by the method of completing square.
Answer:
We have,
2x2−5x+3=0
⇒x2−25x+23=0 (Dividing throughough by 2)
⇒x2−25x=−23 (Shifting the constant term on RHS)
⇒x2−2(45)x+(45)2=(45)2−23 (Adding (21Coeff.ofx)2 onboth sides)
⇒(x−45)2=1625−23⇒(x−45)2=16
Answer:
Next term = -16
Step-by-step explanation:
0-4 = -4
(-4)-0 = -4
(-8)-(-4) = -4
(-12)-(-8) = -4
It’s clear that Un is an arithmetic sequence of common difference r = -4
Then
Next term :
Answer:
No
Step-by-step explanation:
If you do the math of 11 x 1.89 sense he wants to buy 11 pairs of socks that are 1.89 each you would get 20.79 being 79 cents over the amount he has.
