Answer:
hope you like the answer
Step-by-step explanation:
Let the score in the first test be x.
Suyash's score in second test is 10 more than that in the first.
So, his score in the second test = x+10
5 times the score of the second test is the same as square of the score in the first test.
5(x+10)=x2
⇒5x+50=x2
⇒x2−5x−50=0
⇒x2−10x+5x−50=0
⇒x(x−10)+5(x−10)=0
⇒(x+5)(x−10)=0
⇒x=10,−5
The score is not negative so, Suyash scored 10 marks in first test.
