Factorise: X(3x + 14) + 8

factorise: x(3x + 14) + 8

Sum

x(3x + 14) + 8

= 3x² + 14x + 8

= 3x² + 12x +2x +8

= 3x(x + 4) + 2(x + 4)

= (x + 4)(3x + 2)

Factorise by the grouping method: 16 (a + b)² - 4a - 4b

Factorise by the grouping method : (ax + by)² + (bx - ay)²

Factorise by the grouping method : a²x² + (ax² + 1) x + a

factorise: 2a² + 7a + 6

factorise: 2x² + xy - 6y²

factorise: 1 - 18x - 63x²
