Answer 2

Answer:

x²-6x+25=0

send 25 to RHS

x²-6x=-25

convert 6x into 2ab form because we are going to use the formula:

a²+b²+2ab= (a+b)²

x²-2.x.3=-25

x²-2.x.3+3²= - 25+3²(add 3² on both sides because it is the b²)

(x+3)²=-25+9

(x+3)² = 16

x + 3 = √16

x+3=4

x = 4 - 3

x =1

hope this helps you
