Answer:
The value of the expression is 2
Step-by-step explanation:
Find the complete question in the attachment.
From the attachment, we are to rearrange the numbers 1, 2, 3, 4, 5 and 6 into the boxes given and get a number closer to zero.
The expression will be in the format below:
a•xⁿ - b(c+d)
Taking a= 1, x = 2, n = 5, b = 3, c=4 d= 6
On substituting
= 1•2^5 - 3(4+6)
= 1•(32) - 3(10)
= 32-30
= 2
Since 2 is greater than 0, hence the arrangements will be first box takes 1, second takes 2, third box takes 5, fourth box takes 3, fifth box takes 4 and sixth box takes 6.
Separate the 1st 2 terms from the 3rd term:
y = x^2 - 8x + 7
Next, take half of the coefficient of x (that is, half of -8).
In this case that'd come out to -4.
Square this -4 and add the result (16) to x^2 - 8x: x^2 - 8x + 16; subtract -16 from 7:
x^2 - 8x + 16 7 - 16
Write the trinomial as
a perfect square:
(x-4)^2 -9
The answer is (x-4)^2 - 9.
This approach is very useful. Note that the vertex of the parabola represented by the given polynomiql is (4,-9).

2+3+1 = 7
£72 / 7 = £10.28
Answer:
£10.28 * 2 = £20.56
£10.28 * 3 = £30.84
£10.28 * 1 = £10.28
If you want to check if it's correct. add all three of them and see if you get the £72.
