X squared plus 10x plus 25 equals 81?
Assuming the expression you want to solve is: x^2 + 10x + 25 = 81 Subtract both sides by 81: x^2 + 10x - 56=0 First, check for factors of 56 whose difference is 10: 2 and 28, no, 4 and 14, yes. So factor the expression as: (x+14)(x-4)=0 Thus the solutions to the expression are either x=4 or x=-14.
What are the roots of 6x2 plus 37x plus 6?
When the given expression equals 0 then x = -1/6 and x = -6
What is the factor expression of x2-9x plus 4 equals 0?
That equation can not be factored. It can however be solved for x: x2 - 9x + 4 = 0 x2 - 9x + 81/4 = 81/4 - 4 (x - 9/2)2 = 81/4 - 16/4 (x - 9/2)2 = 65/4 x - 9/2 = ± √65 / 2 x = (9 ± √65) / 2
