FACTORING TRINOMIALS

  • 25a²  - 30ab + 9b²=(5a-3b)²
  • 3x² + 6xy + 3y²=3(x²+2xy+y²)=3(x+y)²
  • x² + 3xy - 10y²=(x+5y)(x-2y)
  • a² + 8a + 16=(a+4)²
  • 9 - 6x + x²=(3-x)²
  • 4a² - 12ax + 9x²=(2a-3x)²
  • 10x - 25 - x²=-(5-x)²
  • 7x + 2x² - 39 doesn’t factorise rationally
  • 2x² - 23x - 39=(2x+3)(x-13)
  • 6m² + 7m - 20=(2m+5)(3m-4)
  • 6x² + 5xy - 6y²=(2x+3y)(3x-2y)
  • 6x² + 13xy - 5y²=(2x+5y)(3x-y)
  • 6x² - 7xy - 5y²=(2x+y)(3x-5y)
  • m² + 4m + 4=(m+2)²
