Question

4 एक्स स्क्वायर प्लस 8 एक्स प्लस 4 इक्वल टू जीरो ​

Answer 1

Answer:

4x² + 8x +4=0

4x² +4x +4x +4 = 0

4x(x+1) + 4(x+1) = 0

(4x+4)(x+1) =0

4x+4= 0 , x+1 = 0

x =-4/4 , x = -1

x = -1 , x= -1

Answer 2

Answer:

Step-by-step explanation:

4x²+8x+4=0

4(x²+2x+1)=0

x²+2x+1=0

x²+(1+1)x+1=0

x²+x+x+1=0

x(x+1)+1(x+1)=0

(x+1) (x+1) =0

either               or

x+1=0               x+1=0

x= -1                  x= -1
