20(x + 3) - (x + 2)(x - 3)
After distributing 20 and multiplying (x + 2) and (x - 3) together:
20x + 60 - (x^2 - 3x + 2x - 6)
After combining like terms:
20x + 60 - (x^2 - x - 6)
After distributing the negative sign to the quantity (x^2 - x - 6):
20x + 60 - x^2 + x + 6
After combining like terms:
- x^2 + 21x + 66
Answer:
20(x + 3) - (x + 2)(x - 3) = - x^2 + 21x + 66

If the product of 1 plus 2 2 plus 3 and 3 plus 4 is equal to one half the sum of 20 and x what is the value of x?
This formula can be better expressed as [(1+2)(2+3)(3+4)] = (20+x)/2. Simplifying, we get 2[(3)(5)(12)] = 20+x. Then the equation becomes 2[180] = 20+x, or 360 = 20+x. Transferring 20 to the other side, we get 360-20 = x. So, x = 340.
What is the answer to 20x plus 3 equals 5?
(20 * x) + 3 = 5 20 * x = 2 x = 1/10
What is x2 plus 12x plus 20?
If you mean: x^2 +12x +20 then it is (x+2)(x+10) when factored
What is x plus x plus 1 plus x plus 2 plus x plus 3 equals -14?
x + x + 1 + x + 2 + x + 3 = -144x + 6 = 144x = 8x = 2
Factor 3x squared plus 3x minus 60?
3x^2+3x-60=3(x^2+x+20)=3(x+5)(x-4)
