i) 3a(5a-2b)
= 15a^2 - 6ab
ii) 5x²(3x+7)
= 15x^3 + 35x^2
ii) x+y+(6x-9)
= 6x^2 + 6xy - 9x - 9y
iv) 4ab(3a-5b+7)
= 12a^2b - 20ab^2 - 28ab
the simplify question is a bit confusing ... please give the whole question in the right format so that I can help in it!!
HOPE IT HELPS :)
PLEASE MARK IT THE BRAINLIEST!
