Integrated Math 1 (help please??:( )

posted by .

You can factor the polynomial f(x)=x^2-19x+70 as (x+a(x+b). The values for a and b are _____.

A. a=10, b=-9

B. a=19, b=70

C. a=-5, b=-14

D. a=-16, b=3

E. none of the above.

  • Integrated Math 1 (help please??:( ) -

    (x+a)(x+b) is what i meant.. sorry!

  • Integrated Math 1 (help please??:( ) -

    ab=70. Which choice does that.

  • Integrated Math 1 (help please??:( ) -

    since 70 = 5*14,

    (x-5)(x-14)

    so, (C)
