(x's square + PX + 2) (X-Q) expansion does not contain quadratic terms about X, then the relationship between P and Q If the result of (- 3x + a) (x-1) does not contain a linear term of X, then the value of constant a is

(x's square + PX + 2) (X-Q) expansion does not contain quadratic terms about X, then the relationship between P and Q If the result of (- 3x + a) (x-1) does not contain a linear term of X, then the value of constant a is

When 1 is expanded to x ^ 3-qx ^ 2 + PX ^ 2 + pqx + 2x-2q, P = q, there is no quadratic term about X
When 2 is expanded to - 3x ^ 2 + 3x + ax-a, a = - 3, there is no linear term about X

How to solve the problem that 1 minus 4 / 3 equals 3 / 5

1-4x/3=3/5,
15-20x=9,
-20x=-6,
x=6/20=3/10.

4X minus eight thirds, x equals one?
