14a^(2)+11ab-15b^(2)

Resolve each of the following quadratic trinomials into factors: 6x^(2)-13xy+2y^(2)(2)14x^(2)+11xy-15y^(2)6a^(2)+17ab-3b^(2)(4)36a^(2)+12abc-15b^(2)c^(2)

Factorise 12a^(2)b+15ab^(2)

Verify the identity (a - b)^(2) -= a^(2) - 2ab + b^(2) geometrically by taking a =11 units, b = 2 units

Verify the identity (a + b)^(2) -= a^(2) + 2ab + b^(2) geometrically by taking a = 11 units, b = 6 unit

Factorise: a^2+14ab-51b^2

Find the sum of the expresson - 15 a ^(2) + 3 ab - 6b ^(2) a ^(2) - 5 ab + 11 b ^(2) , - 7a ^(2)- 18 ab - 13 b ^(2) and 26 a ^(2) - 16 ab - 7b ^(2).

Factorise the expression using the identity a ^(2) + 2 ab + b ^(2) = (a + b) ^(2) x ^(2) + 14x + 49

Factorise the using the identity a ^(2) - 2 ab + b ^(2) = (a -b) ^(2). y ^(2) - 14 y + 49

If a+b+c=14anda^(2)+b^(2)+c^(2)=96 then (ab+bc+ca)=?
