First step of the equation is to simplify the equation 2a • b = a2 + b2 into 2 ab = a2 + b2. This cannot be factored anymore although. when we try to substitute a with 5 and b with 2, the answer in the right hand side of the equation is -9. hence the answer to this problem is false. we can try another values to verify.
Answer:
43+(x-7)=90
43+(x-7)-43=90-43
(x-7)=46
x-7+7=47+7
x=54
