Answer:
[tex]([7]x+[2])^2[/tex]
Step-by-step explanation:
Given:
[tex]49x^2+28x+4[/tex]
We need to factorize the given trinomial.
To solve the above expression we will Split the product of first term and third term to get the second term by either adding or subtracting.
So we get;
[tex]49x^2+14x+14x+4\\\\7x(7x+2)+2(7x+2)\\\\(7x+2)(7x+2)\\\\(7x+2)^2[/tex]
Hence Final Answer is:
[tex]([7]x+[2])^2[/tex]
