4000 milliliters are in 4 liters
Hello : let A(-1,5) B(5,-4)<span>
<span>the slope is : (YB - YA)/(XB -XA)
(-4-5)/(5-(-1)) =-9/6 = -3/2</span></span>
1) x³ + 2x² - x - 2 2) 2x³ + 5x² - 8x - 20 = 0
x²(x + 2) - (x + 2) x²(2x + 5) - 4(2x + 5) = 0
(x + 2)(x² - 1) (2x + 5)(x² - 4) = 0
(x + 2)(x - 1)(x + 1) x = -5/2, +-2
x = -2, 1, -1 << a is the answer.
hope that helps, God bless!
