Simplify the expression 5x − (3x2 + 9x)?
5x-(3x^2 + 9x)=5x-3x^2 -9x=-4x-3x^2 D=16 x1=0 x2=-4/3 a(x-x1)(x-x2)=-3(x-0)(x+4/3)=-3x(x+4/3) So : 5x − (3x^2 + 9x)=-3x(x+4/3)

How do you solve this in elimination method 3a = 2b +1 and 3b = 5a - 3?
This can be solved in two ways.By eliminating 'a'.By eliminating 'b'.(1) By eliminating aTo eliminate A we have to equalize the terms containing A. It can be done by multiplying first equation by 5 and second by 3.3a = 2b + 13a - 2b - 1 = 0 …..(1) × 53b = 5a - 35a -3b - 3 = 0 …..(2) × 315a - 10b - 5 = 0 …..(3)15a - 9b - 9 = 0 …..(4)Subtracting (4) from (3) we get-b + 4 = 0b = 4Now replacing the value of b in any one of the above equations we get3a - 2(4) - 1 = 03a = 9a = 3(2) By eliminating bTo eliminate B we have to equalize the terms containing B. It can be done by multiplying first equation by 3 and second by 2.3a - 2b - 1 = 0 …..(1) × 35a - 3b - 3 = 0 …..(2) × 29a - 6b - 3 = 0 …..(5)10a - 6b - 6 = 0 …..(6)Subtracting (5) from (6) we geta = 3Now replacing the value of a in any one of the above equations we get3(3) - 2b - 1 = 0-2b + 8 = 0b = 4Thus we get the values of a and b by elimination.Thanks for reading.Please do upvotes.Peace.
