4x2 +49

(2x )(2x ) ( +7)( +7)

(2x+7)(2x+7)

Factor:

(2x+7)(2x+7)

Check:

(2x+7)(2x+7)

(2x)(2x) (2x)(+7) (+7)(2x) (+49)

4x2 14x 14x +49

4x2+28x+49

Check:

(2x+7)(2x-7)

(2x)(2x) (2x)(-7) (+7)(2x) (+7)(-7)

4x2 -14x +14x -49

4x2 -49

Check:

(2x-7)(2x-7)

(2x)(2x) (2x)(-7) (-7)(2x) (-7)(-7)

4x2 -14x -14x +49

4x2-28x+49

Can not be factored
