What is the solution of the equation (4x + 3)2 = 18?

x = StartFraction 3 Over 2 EndFraction and x = –3
x = StartFraction negative 3 Over 2 EndFraction and x = 3
x = StartFraction negative 3 + 3 StartRoot 2 EndRoot Over 4 EndFraction and x = StartFraction negative 3 minus 3 StartRoot 2 EndRoot Over 4 EndFraction
x = StartFraction 3 + 3 StartRoot 2 EndRoot Over 4 EndFraction and x = StartFraction negative 3 + 3 StartRoot 2 EndRoot Over 4 EndFraction

Step-by-step explanation:

open brackets by multiplying with 2

8x+6=18

8x=12

x=3/2

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
