Step-by-step explanation: x 2 +3x+1=(x−2) 2 x 2 +3x+1=x 2 −4x+4 ⇒x 2 +3x+1−x 2 +4x−4=0 ⇒7x−3=0 has its highest power 1 Hence it is not a quadratic equation Reply
Step-by-step explanation:
x
2
+3x+1=(x−2)
2
x
2
+3x+1=x
2
−4x+4
⇒x
2
+3x+1−x
2
+4x−4=0
⇒7x−3=0 has its highest power 1
Hence it is not a quadratic equation
