Question

In a T 20 cricket match A and B together scored 150 runs. If both of them Scored 20 runs more than product of their runs become 7000" Write a quadratic equation representing the situation.​

Answer 1

Hey mate ,

A + B = 150

Thus

B = 150 - A

also

(A+20)(B+20) = 7000

putting the value of B

(A+20)(150-A+20)=7000

(A+20)(170-A)= 7000

170A - A^2 +3400 -20A= 7000

0 = A^2 -150 +7000-3400

thus quadratic equation so formed is

A^2 -150A + 3600
