Do the math ( 4x -3)^2?

Answer 1

(4x - 3)² =

(4x - 3)(4x - 3) =

16x² - 12x - 12x + 9 =

collect like terms

16x² - 24x + 9

- - - - - - - s-

Answer 2

Expand the expression: (4x - 3)(4x - 3)
Use distribution, the answer is

16x^2 - 24x + 9

Answer 3

Hey there!

Here's the answer.

(4x-3)^2 --> Write the problem.
(a-b)^2 --> Substitute a for 4x and b for 3.
a^2-2ab+b^2 --> Use the formula (a-b)^2=a^2-2ab+b^2.
(4x)^2-2(4x)(3)+(3)^2 --> Substitute 4x for a and 3 for b.
16x^2-24x+9 Simplify the above expression.

So the answer is 16x^2-24x+9.

Hope it helps!

Answer 4

when expanding squares, as this problem is, you have to learn this short song:

square the first term
put down the given sign then
double the first term times the last term
plus the square of the last term

do 5 or 6 of these type problems and repeat the above song enough times and you will do these problems in your sleep.

Answer 5

(4x-3)(4x-3)
16x^2 - 12x - 12x + 9
16x^2-24x+9

Answer 6

i think it'll be ( 16x^2 -9)
what is that summer homework? seriously after you finish solving this nonsense i suggest you switch on the tv and just relax.
school sucks
