Question

X square + 30 x is equal to 7000 ​

Answer 1

Answer:

Step-by-step explanation:

1.1     Factoring  x2+30x+7000  

The first term is,  x2  its coefficient is  1 .

The middle term is,  +30x  its coefficient is  30 .

The last term, "the constant", is  +7000  

Step-1 : Multiply the coefficient of the first term by the constant   1 • 7000 = 7000  

Step-2 : Find two factors of  7000  whose sum equals the coefficient of the middle term, which is   30 .

     -7000    +    -1    =    -7001  

     -3500    +    -2    =    -3502  

     -1750    +    -4    =    -1754  

     -1400    +    -5    =    -1405  

     -1000    +    -7    =    -1007  

     -875    +    -8    =    -883  

For tidiness, printing of 58 lines which failed to find two such factors, was suppressed

Observation : No two such factors can be found !!
