2x² + 3x - 5 = 0
a=2, b=3, c=-5
D = b² - 4ac = 3² - 4*2*(-5) = 9 + 40 = 49
The commutative porperty states that numbers can be swapped over , they can change their place in the equation and the result will still be the same.
In our case 13 x 7 x 21, the commutative property means that the numbers can be rearranged
13x7x21=13x21x7=7x21x13=7x13x21
They intersect at a point called the centroid. See the attached sketch.
Yes
