use shift-8 for multiplication next time,
if you want, change the question or rephrase it in addition details.
if it is 42-(7*2)^2+3*â(25)
then the answer is 42-(5^2)+3*5
. . . . . . . . . . . . . . 42-(25)+15
. . . . . . . . . . . . . . . 42-10

42 - 7x² + 3â25 =
42 - 7x² + 3•5 =
42 - 7x² + 15 =
57 - 7x²
but there's no more you can do unless you have a value for x.
