User: Factor this expression completely. 18x4 + 12x2y + 2y2

Weegy: 18x^4 + 12x^2y + 2y^2 = 2(9x^4 + 6x^2 + y^2) = 2(3x^2 + y)^2


User: Factor this expression completely. 2x2 + 11x + 15

Weegy: 2x^2 + 11x + 15
= 3(2x + 5) + x(2x + 5);

(a + b)(a - b)
= a*a + b*a - a*b - b*b
= a^2 + ab - ab - b^2
= a^2 - b^2

(r + s)(r^2 - rs + s^2)
= r^3 + sr^2 - r^2s - rs^2 + rs^2 + s^3
= r^3 + 0 + s^3
= r^3 + s^3

(2a^2 - 8)(4a^4 + 16a^2 + 64)
= 8a^6 - 32a^4 + 32a^4 - 128a^2 + 128a^2 - 512
= 8a^6 + 0 - 512
