Question

one factors of x^2-36 is? a)x+4 , b) x+3 , c)x+9 or d) x+6​

Answer 1

Answer:

x^2-36

x^2=36

x=+ or - square root of 36

x=+-6

therefore x+6 is a factor of x^2-36

Step-by-step explanation:

Answer 2

Answer:

(d) x + 6

Step-by-step explanation:

First lets factor x^2 - 36

We know x^2 - y^2 = (x + y)(x - y)

So x^2 - 36 = x^2 - 6^2 = (x + 6)(x - 6)

Here (x + 6) is a factor and is an option as stated in question.

Therefore, answer is (d) x + 6
