Hello from MrBillDoesMath!
Answer:
(x+3)^2 -15 = 0
Discussion:
To complete the square add (and then subtract) the square of one-half the coefficient of x:
x^2 + 6x -6 = 0 =>
-- complete the square part --
x^2 + 6x + (6/2)^2 - (6/2)^2 - 6 = 0 =>
x^2 + 6x + 9 - 9 - 6 = 0 => as 6/2 = 3
(x + 3)^ 2 - 9 - 6 = 0 =>
(x+3)^2 -15 = 0
We can solve this as follows:
(x+3)^2 = 15 take square root of both sides
(x+3) = +\- sqrt(15)
x = -3 +\- sqrt(15)
Thank you,
MrB
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
