Written as a simplified polynomial in standard form, what is the result when (2x - 7) ^ 2 is subtracted from 1?

zaharov [31]

ans: -4( x-3 )( x-4 ) I.e -4( x² + x - 12 )

Step-by-step explanation:

as per question

1- (2x-7)²

Write an equation in point-slope form of the line that passes through the point (9,0) and has a slope of m=-3 .

aksik [14]

Answer:

$y = - 3x + 27$

Step-by-step explanation:

The standard form for the equation of the line is

$y = mx + c$

Recall that:

$y = 0 \: \: \: x = 9 \: \: \: m = - 3 \\ y = mx + c \\ 0 = - 3(9) + c \\ 0 = - 27+ c \\ 27 = c$

Therefore the equation of the line is:

$y = mx + c \\ y = - 3x + 27$

Expand (3x+2)^4 and show your work.

AysviL [449]

You have to distribute the exponent of 4 to the whole equation.
so step one is to distribute to the 3
3^4= 81
then we have to distribute to the x
x^4
then to the 2
2^4= 16
81 * x^4 * 16
* = multiplication sign
