Question

Factorise
x^2-10+120=0

Answer 1

Answer: I think your question is x²-10x+120

Please mark the brainliest!..

It is hard to proceed using factorization!..use quadratic formula or complete the square method!

*Complete the square method!*

x²-10x+120=0 (Make the coefficient of x² as 1) •(already 1 so no need to do anything.)

x²-10x = -120 (shifting the constant to the RHS!)

x²-10x+(5)²=(5)²-120 (Divide the coefficient of x by 2 and add the squares on both hand sides)

(x-5)²=25-120

(x-5) = ±√95

x = 5±√95

(1) x = 5+√95 = 14.746 ,

(2) x = 5-√95 = -4.746

(Ans)

Answer 2

Answer:

Explanation:

X^2-10+120=0

X^2 +110. =0

X^2. = -110

-x^2. = 110

= √110

= -√110
