`{ x }^( 2 ) -7x+12`

Answer 1

Yore answer here is 4 ….

Answer 2

x is 3 or 4

Explanation:

• I assume that you want to find the solutions for this quadratic equation
• First of all, set it all to equal 0
• 
  `x^(2)-7x+12=0`
• 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:
• 
  `(x-3)(x-4)=0`
• 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
