Question

What do the answer to this question
X2-13x+36

Answer 1

x2 + 13x + 36 = 0

36 + 13x + x2 = 0

(9 + x)(4 + x) = 0

9 + -9 = 0 0 + x = 0 + -9 x = 0 + -9



 x^2 - 13x + 36 = 

(x - 9)(x - 4) = 0 


4² - 13(4) + 36 = 0 

16 - 52 + 36 = 0 

-36 + 36 = 0 
0 = 0 

9² - 13(9) + 36 = 0 

81 - 117 + 36 = 0 

-36 + 36 = 0 

0 = 0 

So the Answer Is x = 9 , 4
