Hi everyone if anyone that is good in math may you me with this

What is the product? (x2+3y+7) [yy+1)

Plz determine whether the polynomial is a difference of squares and if it is, factor it. y2 – 196 is a difference of squares: (y + 14)2 is a difference of squares: (y – 14)2 is a difference of squares: (y + 14)(y – 14) is not a difference of squares

Solutions for 2x+7 less than or equal to 3x-5
