Expand (2x - 4)2 using the square of a binomial formula. (x)2 + 2(x)(4) + 42
O (2x)2 + 2(2x)(4) - 42
O(x2 - 2(x)(4) - 42
(2x)2 - 2(2x)(4) + 42

Step-by-step explanation:

We have to expand,

(2x — 4)²

(2x)² + (4)² ― 2(2x × 4)

4x² + 16 ― 2(8x)

4x² + 16 ― 16x

4x² ― 16x + 16

Hence, solved!

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
