Answer:
7.4*10^-5, 7300000
Step-by-step explanation:
1 There are 4 zeros in 1
round up .0000742 to .000074
There are 5 places between 7 and the last zero, negative because it is a decimal.
2 7.3*10^6= 73 is first, 6 places after 7 so 5 zeros (6 is in a place)
ANSWER : (9u - 8)2
STEPS:
Step-1 : Multiply the coefficient of the first term by the constant 81 • 64 = 5184
Step-2 : Find two factors of 5184 whose sum equals the coefficient of the middle term, which is -144 .
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -72 and -72
81u2 - 72u - 72u - 64
Step-4 : Add up the first 2 terms, pulling out like factors :
9u • (9u-8)
Step-5 : Add up the four terms of step 4 :
(9u-8) • (9u-8)
Which is the desired factorization
1. -3
2. 28
3. 88
4. -5
5. -28
Get unknowns on one side and know on other side.
Divide both sides by -2
X= -7
