Question

xsquare +13x+65 factorize ​

Answer 1

Answer:

x²+18x+65

x²+13x+5x+65

x(x+13)+5(x+13)

(x+13)(x+5)

hope it helps you and don't forget to follow me

Answer 2

x²+13x+65 = 0

comparing with x²+bx+c =0 ; a = 1 ,b = 13 , c= 65

now by sridharacharya formula ,

x = [-b±√( b²-4ac) ]/2a

x = [-13±√( 169 - 260 )]/2

°•° we can see that there is a possibility of getting a negative number inside a square root so the question is invalid

so it wud help us a great deal to help u if u put up the correct ques ..if this is only the correct ques then the ans is given above ...good ques though based on concept
