Question

Simplify (−8b)(−15b).
120b2
−120b2
120b
−120b

Answer 1

`120b^2`

Explanation:

When multiplying two terms, multiply the coefficients and the variables.

Also, remember the rules for multiplying integers:

• negative * positive = negative
• negative * negative = positive
• positive * positive = positive

-8 * -15 = +120

b * b =
`b^2`

∴(-8b)(-15b) =
`120b^2`

Answer 2

`(-8b)(-15b)`

`(-8)* b*(-15)* b`

`120* b^2`

`=120b^2`
