Question

(x-4)^2+5=(x+2)^2-(9-14x)​

Answer 1

Answer:

(x-4)²+5= (x+2)²-(9-14x)

(x)²-2.x.4+(5)²= (x)²+2.x.2+(2)²-(9-14x)

x²-8x+25=x²+4x+4-9+14x

x²-x²-8x-4x-14x= -25-9+4

-26x=-34+4

-26x= -30

x= -30/-26

hence ,x= 30/26 = 15/13 Ans.

Answer 2

Answer:

(x-4)²+5=(x+2)²-(9-14x)​

(x²-8x+16)+5= (x²+4x+4)-(9-14x)

x²-8x+16+5= x²+4x+4-9+14x

x²-8x+21= x²+18x-5

x²-8x= x²+18x-26

x²-8x-(x²+18x)=x²+18x-26(x²+18x)

-26x=26

x=1
