Answer:
Step-by-step explanation:
[tex](-5y^2-9y-4)-(-2y^2-y+8)[/tex]
To find the opposite of [tex]-2y^2-y+8[/tex], find the opposite of each term.
[tex]-5y^2-9y-4+2y2+y-8[/tex]
Combine [tex]-5y^2[/tex] and [tex]2y^2[/tex] to get [tex]-3y^2[/tex].
[tex]-3y^2-9y-4+y-8[/tex]
Combine -9y and y to get -8y.
[tex]-3y^2-8y-4-8[/tex]
Subtract 8 from -4 to get -12.
[tex]-3y^2-8y-12[/tex]
[tex](3x-2)(5x^2-7x+2)[/tex]
Use the distributive property to multiply [tex]3x-2[/tex] by [tex]5x^2-7x+2[/tex] and combine like terms.
[tex]15x^3-31x^2+20x-4[/tex]
[tex](x-1)(3x-2)(5x-2)[/tex]
Hope this helps! Brainliest would be much appreciated! Have a great day! :)
