what is 7x to the third power + 6x to the second - 2
Let the number be x: 7x-6 = -20 7x = -20+6 7x = -14 x = -2
(x + 4)(x^2 + 3x + 2) = x^3 + 7x^2 + 14x + 8
7x-4=x+2 7x=x+2+4 7x=x+6 7x-x=6 6x=6 X=1
2 to the power 0 or 20 is equal to 1
7x-2
what is 7x to the third power + 6x to the second - 2
7x = 2 = 51 is not a valid equality. 2 cannot be equal to 51.

(4)(2)+7x-28+7x-27x-6.This expression cannot be simplified further nor solved (because it is not equal to anything).
14x squared minus 7x to the 3rd power can be factored to 7x2(2-x).
If you mean: -2(3x-3) = 7x-2 then the value of x works out as 8/13
7x = 4x+2x+1xSo 7x/2 = 4x/2 + 2x/2 + x/2 (by the distributive property of division over addition) = 2x + x + x/2
Let the number be x: 7x-6 = -20 7x = -20+6 7x = -14 x = -2
hujkImproved anwser:2x+6 = 7x-42x-7x = -4-6-5x = -10x = 2
Try to factor the left side and set each of the linear expressions equal to zero. 7x^2 +8x -12= 0 (7X-6)(X+2)=0 7X-6=0 X=6/7 X+2=0 X=-2
The area of square is : 49.0
