A student is deriving the quadratic formula. Her first two steps are shown. Step 1: –c = ax2 + bx

Step 2:

Which best explains or justifies Step 2?

division property of equality
factoring the binomial
completing the square
subtraction property of equality

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.

but which class are u may know that first
