Question

the standard form of the quadratic equation 3x2=4(5x-3)is


​

Answer 1

Answer:

hi

Step-by-step explanation:

The standard form of the quadratic equation 3x2 = 4(5x – 3) isA. 3x2 - 5x + 3 = 0B.

Answer 2

Answer:

ax2+bx+c=0

The solution is

x=−b±√b2−4ac2a

The discriminant Δ is b2−4ac.

The discriminant "discriminates" the nature of the roots.

There are three possibilities.

If Δ>0, there are two separate real roots.

If Δ=0, there are two identical real roots.

If Δ<0, there are no real roots, but there are two complex roots.

Your equation is

3x2–5x+4=0

Δ=b2–4ac=(−5)2−4×3×4=25–48=−23

This tells you that there are no real roots, but there are two complex roots.

We can see this if we solve the equation.

3x2–5x+4=0

x=−b±√b2−4ac2a=−(−5)±√(−5)2−4×3×42×3=5±√25−486=5±√−
