Answer:

Standard Form:

  1. 3x² - 2x + 5
  2. x² + 5x - 4 = 0
  3. 2x² - 3x - 20 = 0
  4. 2x² - 2x - 6 = 0
  5. x² + 5x - 4 = 0

Values of a, b, c:

  1. 3, -2, 5
  2. 1, 5, -4
  3. 2, -3, -20
  4. 2, -2, -6
  5. 1, 5, -4

Step-by-step explanation:

1.

[tex]2x - 3 {x}^{2} = 5 \\ - 3 {x}^{2} + 2x - 5 = 0 \\ - 1( - 3 {x}^{2} + 2x - 5 = 0) -1 \\ 3 {x}^{2} - 2x + 5 = 0[/tex]

2.

[tex]4 - {x}^{2} = 5x \\ - {x}^{2} - 5x + 4 = 0 \\ - 1( - {x}^{2} - 5x + 4 = 0) - 1 \\ {x}^{2} + 5x - 4 = 0[/tex]

3.

[tex](2x + 5)(x - 4) = 0 \\ 2 {x}^{2} - 8x + 5x - 20 = 0 \\ 2 {x}^{2} - 3x - 20 = 0[/tex]

4.

[tex]2x(x - 1) = 6 \\ 2 {x}^{2} - 2x = 6 \\ 2 {x}^{2} - 2x - 6 = 0[/tex]

5.

[tex](x + 1)(x + 4 ) = 8 \\ {x}^{2} + 4x + x + 4 = 8 \\ {x}^{2} + 4x + x + 4 - 8 = 0 \\ {x}^{2} + 5x - 4 = 0[/tex]
