Understanding quadratic equations in one variable

Standard Form of a quadratic equation is y =

• (x + a)(a + b)

• ax² + bx + c

• (x - h)² + k

• mx + b

 $f\left(x\right)=x^2-x-3$  is Standard Form or Vertex Form or Factored Form

• Standard Form

• Vertex Form

• Factored Form

Which answer is in standard form?

What is a, b, and c in y = 3x² - 5x + 4

• a = 3, b = -5, c = 4

• a = 3, b = 5, c = 4

• a = 3, b = 5, c = -4

• a = 3, b = -5, c = -4

What is the value of "b" in the following equation: 3x² - 2x - 16 = 0?

• -2x

• 2

• -2

• 2x

What is the standard form for a Quadratic function?

• ax²+ bx = - c

• x = -b ± √(b²-4ac) / 2a

• ax² + bx + c = 0

• y = mx + b

Identify the a, b and c of the equation  $3x^2+5x-7$  .
