Question

(25b + 3)(25b – 3)
Multiple the binomials.

Answer 1

`\large\boxed{625b^2 - 9}`

Explanation:

In this question, we would need to solve the binomial to get an expression.

To do this, we need to multiply each number with each other. Starting from the inner numbers, up until the outer numbers are finished.

The equation we are using is:

`(25b + 3)(25b - 3)`

Now, you solve:

`(25b + 3)(25b - 3)\\\\\text{Start by making your multiplication equations}\\\\\text{You woulkd be multplying:}\\\\25b * 25b\\\\25b * -3\\\\3 * 25b\\\\3*-3\\\\\text{Multiply:}\\\\25b * 25b=625b^2\\\\25b * -3=-75b\\\\3 * 25b=75b\\\\3*-3=-9\\\\\text{You would end up with:}\\\\625b-75b+75b-9\\\\\text{Now, you can just combine like terms}\\\\625b-75b+75b-9\\\\550b+75b-9\\\\\boxed{625b^2-9}`

When you're done solving, you should get 625b² - 9

I hope this helped you out.

Good luck on your academics.

Have a fantastic day!
