Julisa multiplied (2x−1)(x+5)(2x-1)(x+5)   and got 2x2−9x−52x^2-9x-5  .

Did she multiply correctly? If not, what was her mistake?

She multiplied correctly.

Her mistake is that the last term should be +5.

2x2−9x+52x^2-9x+5  

Her mistake is that the first term should be 1, not 2.

1x2−9x−51x^2-9x-5  

Her mistake is that the middle term should be +9x.

2x2+9x−52x^2+9x-5
