Factoring quadratics

Mathematics
1 answer:
Sonja [21]3 years ago
3 0

Answer:

Step-by-step explanation:

by synthetic division

x+8=0

x=-8

-8| 1  -1  -72

  |    -8 +72

------------------

     1  -9 | 0

x-9

width=x-9

or second method

x²-x-72=0

x²-9x+8x-72=0

x(x-9)+8(x-9)=0

(x-9)(x+8)=0

we know area of rectangle=length×width

if length=x+8

then width=x-9
