The binomial expansion 625x4 – 7,500x3 + 33,750x2 – 67,500x + 50,625 can be expressed as (ax + b)4. What is the value of b?

Astandard deck of cards contains 52 cards. one card is selected from the deck. (a) compute the probability of randomly selecting a seven or king. (b) compute the probability of randomly selecting a seven or king or jack. (c) compute the probability of randomly selecting a queen or spade.

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

Solve each quadratic equation by factoring and using the zero product property. 10x + 6 = -2x^2 -2
