Question

5x²-2x-3=0 by formula method​

Answer 1

Answer:

We usually discuss the nature of the roots of the quadratic equation. However, the nature of the equation is that it is factorizable, with real roots such that

(5x+3)(x−1)=0(5x+3)(x−1)=0

The graph crosses the x-axis twice at x=1x=1and x=−35x=−35, which are its roots.

For this equation,

dydx=10x−2dydx=10x−2

So the equation has an extreme value at;

10x−2=010x−2=0

So x=0.2x=0.2

Small excursions around this value such as x=0.19x=0.19 and x=0.21x=0.21 show that the x=0.2x=0.2is a resting point (point of inflection) as the curve continues evolving.

d2ydx2=10d2ydx2=10 shows that the curve gets steeper at an increasing rate as x increases.
