('x' times 'x') plus 'x' = 30x2 + x - 30 = 0(x + 6) (x - 5) = 0x = -6and/orx = 5
30x1= 30 30x2= 60 30x3= 90 30x4= 120 30x5= 150 30x6= 180 30x7= 210 30x8= 230 30x9= 270 30x10= 300 30x11= 330 30x12= 360 UR WELCOME!
Factors are (3x - 2)(10x - 2) so x = 2/3 or 1/5 Check: 30 x 4/9 - 26 x 2/3 = 120/9 - 52/3 = -12/3 = -4 OK 30 x 1/25 - 26/5 =30/25 - 26/5 = 6/5 - 26/5 = 20/5 = -4 OK 60
30x2+25x-24x-20 = 30x2+x-20 = (6x+5)(5x-4) when factored
30x2-23x-14 = (6x-7)(5x+2) when factored with the help of the quadratic equation formula
60x3
Calculate 30x1, 30x2, 30x3, etc.
no because 30x2 is 60 not 90
I understand this expression to be 10x3 + 5x. Derivative: 30x2 + 5.
2(5x - 1)(3x - 2)
x=1/3,3/5
5x(7xy + 6x + 8)
Simply double every place like so 38x2=30x2+8x2=76
5x(6x + 9y + 2)
30 30x1=30 30x2=60 30x3=90
