Raul simplified the expression, as shown below.–[3h + 7h(2 – h)] = –[10h(2 – h)] = –[20h – h] = –19hDescribe the error(s) in Raul’s work.
Answer
Answer:
Raul should have distributed 7h through (2 − h) before combining terms. He also failed to multiply 10h by −h; that product is −10h². The correct simplification is −17h + 7h².
