How to write the standard form of the quadratic equation?

• ax + x + c = 0

• ax² + bx = c

• ax² + bx + c = 0

• c + bx + ax² = 0

What is the value of b in the equation 2x² + 4 - 6x =0

• -6

• 4

• -2

• 1

Write in the standard form 7 + 2x = 5x²

• 5x² + 2x + 7 = 0

• -5x² +2x + 7 = 0

• -5x² + 7 + 2x = 0

• 2x + 7 + -5x² = 0

Determine the values of
a, b, and c for
the quadratic equation:
