Question

"If 4x2 -- 5x + 5 = p and X2 = 1, find the value of 2p2.​

Answer 1

Answer:

Step-by-step explanation:

X2 =1.     (1)

X =under root 1=1.     (2)

   

4(1) -5(1)+5 =p.  ( from 1 and2)

4-5 +5 =p

4=p

 

2p2

2(4) 2

2(16)

32

Answer 2

Answer:

32 is correct

Step-by-step explanation:

4x2-5x+5=p

4(1)-5(1)+5=p. (because √1=1 so, x also

4-5+5=p. equal1)

4-0=p

p=4

so,

2p2=2(4)2=2×16=32
