" c.Factorize the given expression completely: "5x^(2)+6x-8

Factorise the given expression completely: 6x^(2) + 7x -5

If (x + 1) and (x - 2) are factors of x^(3)+ (a + 1)x^2 -(b - 2) x-6, find the values of a and b. And then, factorise the given expression completely.

factorize the given expression 6x^2-5x-21

factorize the given expression 9x^2+18x+8

factorize the given expression 3x^2-14x+8

factorize the given expression 2x^2+3x-90

factorize the given expression 2x^2-7x-15

factorize the given expression x^2-y^2+6y-9

factorize the given expression 6x^2-11x-35

Show that 2x+7 is a factor of 2x^(3)+5x^(2)-11x-14 . Hence factorise the given expression completely, using the factor theorem.
