Question

2
and D, equals, minus, x, plus, 3, commaD=−x+3, find an expression that equals 3, C, minus, D3C−D in standard form.

Answer 1

To find the expression that equals 3C - D, we substitute the values of C and D:

3C - D = 3(x - 9x^2) - (-x + 3)

Simplifying the expression:

= 3x - 27x^2 + x - 3

Now, combining like terms:

= -27x^2 + 4x - 3

So, the expression that equals 3C - D in standard form is -27x^2 + 4x - 3.
