Answer:

x is 3 or 4

Step-by-step explanation:

  • I assume that you want to find the solutions for this quadratic equation
  • First of all, set it all to equal 0
  • [tex]x^{2}-7x+12=0[/tex]
  • Now you need to factorise your expression
  • You need to find two numbers that multiply together to make 12, and ad together to make -7
  • These two numbers are -3 and -4
  • Your new equation is:
  • [tex](x-3)(x-4)=0[/tex]
  • For this equation to equal 0, just one of x - 6 and x - 1 has to equal 0
  • For x - 3 to equal 0, x has to be 3
  • For x - 4 to equal 0, x has to be 4
  • x = 3 or 4
