Question

How do you multiply `-5( - 3y ^ { 2} + 4- 6u ^ { 3} )`?

Answer 1

See a solution process below:

Explanation:

Multiply each term within the parenthesis by the term outside the parenthesis:

`color(red)(-5)(-3y^2 + 4 - 6u^3) =>`

#(color(red)(-5) xx -3y^2) + (color(red)(-5) xx 4) - (color(red)(-5) xx xx 6u^3) =>#

`15y^2 + (-20) - (-30u^3) =>`

`15y^2 - 20 + 30u^3`
