2(2x-11)(3x+5)
you factor out the common 5so it would be: 5(x + 2)so that when you multiply back out 5 by x you get 5x and 5 by 2 you get 10

45 30/12 = x/18; 12x = 30 x 18; 12x = 540; x = 540 ÷ 12 = 45
2*2 - 12x +16 =0 4 - 12x +16 =0 -12x + 16 +4 =0 -12x + 20 =0 -12x = -20 x = 1.666666667

It is: 6(2x-5) when factorized
With the help of the quadratic equation formula
2(2x-11)(3x+5)
12x-30=114 12x=114+30 x=144 / 12 therefore x=12
4x2 + 12x + 5 = 4x2 + 2x + 10x + 5 = 2x(2x+1) + 5(2x+1) = (2x+1)(2x+5)
30+12x = 6(5+2x)
The Greatest Common Factor (GCF) is: 6
12: 1, 2, 3, 4, 6, 12 30: 1, 2, 3, 5, 6, 10, 15, 30 12 + 30 = 42 42: 1, 2, 3, 6, 7, 14, 21, 42 12x + 30 = 6(2x + 5) 12 + 30x = 6(5x + 2)
Use algebra. 12x+30=15x-20. Add 20 to both sides. 12x+50=15x. Subtract 12x from both sides. 50=3x. Divide both sides by 3. 16.666...=x
you factor out the common 5so it would be: 5(x + 2)so that when you multiply back out 5 by x you get 5x and 5 by 2 you get 10
6a -12b + 30 = 6 (a - 2b + 5)
