Subtract 9 from both side of the equation : X = − y + 3, y ≥ 0. Y = x2 −6x +9. N 1 ⋅ n 2 = a ⋅ c = 1 ⋅ 9 = 9 and n 1 + n 2 = b = 6 after trying out a few numbers we get n 1 = 3 and n 2 = 3 3 ⋅ 3 = 9, and 3 +3 = 6 x2 +6x + 9 X = 3 x = 3 Web algebra factor x^2+6x+9 x2 + 6x + 9 x 2 + 6 x + 9 rewrite 9 9 as 32 3 2. X2 + 6x+32 x 2 + 6 x + 3 2 check that the middle term is two times the product of the numbers being squared in the first term and third term. Take the coefficient of x , which is 6 , divide by two, giving 3 , and finally square it giving 9 add 9 to both sides of the equation : Steps for completing the square. X2 +6x + 9 we can split the middle term of this expression to factorise it in this technique, if we have to factorise an expression like ax2 + b + c, we need to think of 2 numbers such that:

On the right hand side we have : Take the coefficient of x , which is 6 , divide by two, giving 3 , and finally square it giving 9 add 9 to both sides of the equation : N 1 ⋅ n 2 = a ⋅ c = 1 ⋅ 9 = 9 and n 1 + n 2 = b = 6 after trying out a few numbers we get n 1 = 3 and n 2 = 3 3 ⋅ 3 = 9, and 3 +3 = 6 x2 +6x + 9 X2 + 2⋅x⋅3+32 x 2 + 2 ⋅ x ⋅ 3 + 3 2 X = 3 x = 3 Y = x2 −6x +9. Web algebra factor x^2+6x+9 x2 + 6x + 9 x 2 + 6 x + 9 rewrite 9 9 as 32 3 2. Web algebra calculator trigonometry calculator calculus calculator matrix calculator. Trinomial squares can be factored by finding the square roots of the leading and trailing terms. On the right hand side we have : X = − y + 3, y ≥ 0.
