    \sqrt{}\sqrt{}Can anyone help me, I'm trying to find the magintude of

    H=(jω+10)^{2}

    |H|= ?


    My attempt, solving it so far.


    H= j^{2}ω^{2}+20jω+100

    H= (-1)ω^{2}+20jω+100


    |H|= sqrt( (-ω^{2}+20jω)^{2}+100^{2})

    But I'm stuck here, any help would be appreciated. Thanks

    Q1) What is the expression for H in the form H=a+jb ?

    Q2) What is the expression for |H| in terms of 'a' and 'b' from Q1?

    Is the answer supposed to be a number or expression?

    Since ω isn't specified, it's going to have to be an expression.
