Solve for p

Mathematics
1 answer:
Natali [406]3 years ago
3 0
√p + 4 + 4 = p
√p  = p - 8
square both sides:-
p  = p^2 - 16p + 64
p^2 - 17p + 64 = 0 

p = 11.372 ,  5.628

Substitute these back into the original equation to check for extraneous roots

p = 11.372 is a genuine root but 5.628 is not

What multiplies to get 14 and adds to get -9
____ [38]
Hi. I  begin by finding the positive factors of 14. They are: 1 x 14 and 2 x 7. None of those can be added to yield a negative number, so let's now instead consider their negatives: -1 x -14 and -2 x -7. Does either of these pairs, when added, yield -9? Yes: -2 and -7.

To be clear: -2 x -7 = 14; and -2 + -7 = -9.

So the answer is -2 and -7.
