Question

simplify of the following questions ​

Answer 1

Answer:

i) 16a^2+3a+2

ii) -x^2-14x^2y^2-3y^2

Step-by-step explanation:

i)15a^2-6a(a-2)+(3+7a)

15a^2-6a^2+2+3a+7a^2

16a^2+3a+2

ii) x^2(1-3y^2)+x(xy^2-2x)-3y(y-4x^2y)

x^2-3x^2y^2+x^2y^2-2x^2-3y^2+12x^2y^2

x^2-2x^2-3x^2y^2+x^2y^2-12x^2y^2-3y^2

-x^2-14x^2y^2-3y^2
