`a^2+2ab +b^2-9c^2`

If x^2+px+1 is a factor of ax^3+bx+c then a) a^2+c^2=-ab b) a^2+c^2ab c) a^2-c^2=ab d) a^2-c^2=-ab

Factorise a^(2)-2ab+b^(2)-c^(2)c^(2)

Divide : 4a^(2) + 12ab + 9b^(2) - 25c^(2) by 2a + 3b + 5c

If a+b+ c=9 and ab + bc +ca = 15 , find : a^2 + b^2 + c^2 .

If a, b and c are distinct positive real numbers such that Delta_(1) = |(a,b,c),(b,c,a),(c,a,b)| and Delta_(2) = |(bc - a^2, ac -b^2, ab - c^2),(ac - b^2, ab - c^2, bc -a^2),(ab -c^2, bc - a^2, ac - b^2)| , then

If ax^2+px+1 is a factor of ax^3+bx+c then a) a^2+c^2=-ab b) a^2+c^2=ab c) a^2-c^2=ab d)a^2-c^2=-ab

If x^(2)+px+1 is a factor of ax^(3)+bx+c then a a^(2)+c^(2)=-ab b) a^(2)+c^(2)ab c) a^(2)-c^(2)=ab d a^(2)-c^(2)=-ab

( a - b) ^(2) + 2ab = ? A. a^(2) - b^(2) B. a^(2) + b^(2) C. a^(2) - 4ab + b^(2) D. a^(2) - 2ab + b^(2)

Subtract the sum of 12ab-10b^2 -18a^2 and 9ab + 12 b^2+ 14a^2 " from the sum of " ab + 2b^2 and 3b^2-a^2 .

Let's find the L.C.M of the following algebraic expressions. 3a^2 - 5ab - 12b^2, a^5 - 27a^2 b^3, 9a^2 + 24ab + 16b^2
