Answer:
£25.50
Step-by-step explanation:
I don't know what you mean by multiplier but to find 85% of £30 you do:
10% of 30 which is 3
80% is 24
5% is 1.5 (to find 5% you find 10% then divide by 2)
Now add 24 and 1.5. Do not add the 10% becuase we used it to help the 80%.
24+1.5=25.5
2x² - 4x = 14
<u>Divide by 2 through:</u>
x² - 2x = 7
<u>Add in the term (b/2)² :</u>
x² - 2x + (2/2)² = 7 + (2/2)²
<u>Complete the square:</u>
(x - 1)² = 7 + 1
<u>Combine like terms:</u>
(x - 1)² = 8
Answer: (x - 1)² = 8
------------------------------------------------------------------------------------------------------------
The question did not ask to solve x. But here is the solution if needed to solve x:
(x - 1)² = 8
x - 1 = ±√8
x = 1 ±√+8
x =1 + 2√2 or x = 1 - 2√2
Answer: x =1 + 2√2 or x = 1 - 2√2
