Expand and simplify (3x-2)^2

1 answer:

5 0

(3x - 2)^2 is the same as:

(3x - 2)(3x - 2)

use the FOIL method: First, Outside, Inside, Last

3x(3x) = 9x²
3x(-2) = -6x
-2(3x) = -6x
-2(-2) = 4

9x² - 6x - 6x + 4

Combine like terms

9x² (- 6x - 6x) + 4

9x² - 12x + 4 is your answer

Suppose you have two hyperbolas that are the same except that the transverse axis and conjugate axis are switched. How does swit

Nonamiya [84]

Check the picture below.

assuming both hyperbolas at centered at the origin, the values for the numerator and denominator will switch, so that the slope of one is the reciprocal of the other's slope.
