Factorize each of the following expressions: a^(2)x^(2)+(ax^(2)+1)x+a3ax-6ay-8by+4bx

Factorise. (i) x^2 + xy + 8x + 8y (ii) 15xy - 6x + 5y - 2 (iii) ax + bx - ay - by (iv) 15pq + 15 + 9q + 25p (v) z - 7 + 7xy - xyz

Factorise. (i) x^2 + xy + 8x + 8y (ii) 15xy - 6x + 5y - 2 (iii) ax + bx - ay - by (iv) 15pq + 15 + 9q + 25p (v) z - 7 + 7xy - xyz

ax+by=1 bx+ay=2

The number of common tangents to the circles x^(2) + y^(2) = 4 and x^(2)+y^(2)-6x-8y=24 is

The number of common tangents to the circles x^(2) + y^(2) = 4 and x^(2)+y^(2)-6x-8y=24 is

The equation of the parabola whose focus is (4,-3) and vertex is (4,-1) is. (A) x^(2)+ 8x+8y – 24 = 0 (B) y^(2) + 8x -8y + 24 = 0 (C) x^(2) – 8x+8y + 24 = 0 (D) y^(2) +8x+8y-24 = 0

f(x)= bx^(2) + cx and d and f(x+ 1) - f(x)= 8x + 3 then…….
