Simply the following polynomials. ANSWERS MUST BE IN STANDARD FORM.
(w-7)(w+3)

w^2-4w-21
Explanation: (w-7)(w+3)
=(w)(w)+(w)(3)+(-7)(w)+(-7)(3)
=w^2+3w-7w-21
=w^2-4w-21

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
