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:
