Question

sum of two number is 30 and their products is224.if one number is 15+x what is second number.forming second degree equation find number

Answer 1

the numbers are 14 and 16

14+16=30
14*16=224

Answer 2

LET THE SECOND NUMBER IS X
SO
$x + 15 + x = 224 \\ 2x + 15 = 224 \\ 2x = 224 - 15 = 209 \\ x = \frac{209}{2} = 104.5$
NOW 1ST NUMBER IS 15+X SO 15+104.5=119.5
2ND NUMBER IS 104.5
