Question

polynomial factories 4x squar-4x-3​

Answer 1

4x2−4x−3=0

⇒4x2−6x+2x−3=0

⇒2x(2x−3)+1(2x−3)=0

⇒(2x−3)(2x+1)=0

⇒2x−3=0 OR 2x+1=0

⇒x=23 OR x=−21

Hence the zeroes of polynomial (4x2−4x−3) are 

23 and −21.

Answer 2

Answer:

4x2−4x−3=0  

⇒4x2−6x+2x−3=0  

⇒2x(2x−3)+1(2x−3)=0  

⇒(2x−3)(2x+1)=0  

⇒2x−3=0 OR 2x+1=0  

⇒x=23 OR x=−21  

Hence the zeroes of polynomial are  23 and −21.
