Factor out

3

from

3 y - 21 : 3 (y - 7)

= x (y - 7) + 3 (y - 7)

y - 7

= (y - 7) (x + 3)

Popular Examples

16 y^{2} + 0 y + 10 = 0

x (x - 1) - 2 x = - 6 x

factor 5x^2+12x+7 factor

5 x^{2} + 12 x + 7

(500*10*70)=(500*10*30)+(1/2*500*x^2)

(500 \cdot 10 \cdot 70) = (500 \cdot 10 \cdot 30) + (\frac{1}{2} \cdot 500 \cdot x^{2})

-(4x+2)-7x=-12x+1

- (4 x + 2) - 7 x = - 12 x + 1
