Factor as the product of two binomials.
x^2+14x+49=

( x + 7 ) ( x + 7 )

Step-by-step explanation:

Product = 49

Sum = 14

Factors = 7 & 7

x² + 14x + 49

( x + 7 ) ( x + 7 )

Step-by-step explanation:

x² + 14x + 49 = x² + 7x + 7x + 7*7

= x*( x+ 7) + 7*(x + 7)

= (x + 7)(x + 7)

step-by-step explanation:

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
