1.) 2s(s-4)

2.) (w+7)(w+3)

3.) (2+ - 1)( t +5 )

4.) (x + 4 ) (x + 4) 

5.) (2r-5) (2r-5)

6.) (3-4m)^2 

7.) (2h + 7) (2h-7) 

8.) (8-3x)(8+3x)

plsssss help plsssssssss

Looking to match the general expression   ax^2 + bx + c

 

1). 2s(s-4) → 2s^2 - 8s :   a = 2,  b = -8,  c = 0.  In this case we have s standing in for x.

 

2).  (w + 7)(w + 3) → w^2 + 10w + 21:   a = 1,  b = 10,  c = 21.  In this case we have w standing in for x.

 

Try the rest yourself.  I assume 3) should be (2t -1)(t + 5) or it won't be a quadratic!
