You can use sum-product but the easiest way is to isolate x like this:
x^2 + 9x (-9x) = 0 (-9x)
x^2 = -9x
x^2 (/x) = -9x(/x)
x=-9
Answer:
A. ..........
Step-by-step explanation:
Answer:
p = -29/2
Step-by-step explanation:
2p + 38 = 9
Subtract 38 from each side
2p + 38-38 = 9-38
2p = -29
divide by 2
2p/2 = -29/2
p = -29/2
Uhh... is this the full problem because this looks like this is half a problem.
