    the GCF is the highest number that we can divide the equation on it in 1st question the 2nd and 4th options are wrong, so you have 2 options the 1st and 3rd now you can decide which one has the GCF

    yea it is produced when a two similar numbers are multiplied each other for example 4*4=16 then 16 is a perfect square similarly (a+b)*(a+b)= \[a ^{2}+2ab+b ^{2}\] this is a perfect square

    so if you want to find the answer factor out each equation, once you have two similar brackets that is your answer

    yes right in simple way look at your equation both 16x^2 and 49 are perfect squares, and -56 is twice the product of 4x and 7 so it's a perfect square
