Answer:

x+63 = 90

Step-by-step explanation:

x and 63 add to a right angle so their sum is 90

x+63 = 90

We can solve

x = 90-63

x = 27

Step-by-step explanation:

<u>Given</u>

  • f(x) = 4x³ + 3x² - 2x - 1

<u>Divide it by the following:</u>

<u>(a) 2x + 1</u>

  • 4x³ + 3x² - 2x - 1 =
  • (4x³ + 2x²) + (x² + 1/2x) - (5/2x + 5/4) + 1/4 =
  • 2x²(2x+1) + 1/2x(2x + 1) - 5/4(2x + 1) + 1/4 =
  • (2x + 1)(2x² + 1/2x - 5/4) + 1/4

Quotient =  2x² + 1/2x - 5/4

Remainder = 1/4

<u>(b) 2x - 3</u>

  • 4x³ + 3x² - 2x - 1 =
  • (4x³ - 6x²) + (9x² - 13.5x) + (11.5x - 17.25) + 16.25 =
  • (2x -3)(2x² + 4.5x + 5.75) + 16.25

Quotient = 2x² + 4.5x + 5.75

Remainder = 16.25

<u>(c) 4x - 1</u>

  • 4x³ + 3x² - 2x - 1 =
  • (4x³ - x²) + (4x² - x) - (2x - 1/2) - 3/2 =
  • (4x - 1)(x² + x - 1/2) - 3/2

Quotient = x² + x - 1/2

Remainder = - 3/2

<u>(d) x + 2</u>

  • 4x³ + 3x² - 2x - 1 =
  • (4x³ + 8x²) - (5x² + 10x) + (8x + 16) - 17 =
  • (x + 2)(4x² - 5x + 8) - 17

Quotient = 4x² - 5x + 8

Remainder = - 17
