Answer: See explanation
Step-by-step explanation:
1. (x + 6)(x - 4)
x (x - 4) + 6 (x - 4)
x² - 4x + 6x - 24
<em>x² + 2x - 24</em>
<em></em>
2. (2x + 5)(x - 3)
2x (x - 3) + 5 (x - 3)
2x² - 6x + 5x - 15
<em>2x² - x - 15</em>
<em></em>
3. (3x + 2)(2x + 5)
3x (2x + 5) + 2 (2x + 5)
6x² + 15x + 4x + 10
<em>6x² + 19x + 10</em>
<em></em>
4. (2x - 1)(x - 5)
2x (x - 5) + -1 (x - 5)
2x² - 10x + -x + 5
2x² - 10x - x + 5
<em>2x² - 11x + 5</em>
<em></em>
Hope that helped!
does it pass through the origin? well, we could draw it, or we can just check that, the origin is at 0,0, or namely when x = 0, y = 0, let's see if that's true, let's make x = 0, let's see what we get for "y".
y = -3(0) + 11 => y = 11
woops, no dice, y ≠ 0, so nope, doesn't pass through the origin.
Yeah it’s c I took that test to
