Q:

rewrite the function f(x)=x^2-6x-60 by completing the square​

Accepted Solution

A:
Answer:      x =(6+√276)/2=3+√ 69 = 11.307 Step by step solution :Step  1  :Trying to factor by splitting the middle term 1.1     Factoring  x2-6x-60 The first term is,  x2  its coefficient is  1 .The middle term is,  -6x  its coefficient is  -6 .The last term, "the constant", is  -60 Step-1 : Multiply the coefficient of the first term by the constant   1 • -60 = -60 Step-2 : Find two factors of  -60  whose sum equals the coefficient of the middle term, which is   -6 .Step-by-step explanation:
