Question

9x^2-169x+400=0..find the value of x

Answer 1

Answer:

X=16 and X=25/9

Step-by-step explanation:

9*400=3600

on multiplying u should get 3600 and on adding u should get -169.

So the two numbers are -144 & -25

divide both by 9.

144/9=16 & 25/9

(x-16)(x-25/9)=0

so the answer is x=16 & x=25/9
