12x^2+10
To simplify (8x \cdot 2x), you multiply the coefficients and the variables separately. First, multiply the coefficients: (8 \times 2 = 16). Then, multiply the variables: (x \cdot x = x^2). Therefore, the simplified expression is (16x^2).
To simplify the expression (8x - 3(2 + 2x)), first distribute the (-3) across the terms inside the parentheses: [ 8x - 3 \cdot 2 - 3 \cdot 2x = 8x - 6 - 6x. ] Next, combine like terms: [ (8x - 6x) - 6 = 2x - 6. ] Thus, the simplified expression is (2x - 6).
2x^8 -16x^7 +10x^6 = 2x^6(x^2 - 8x + 5)
16x-8x+12 = 78+22 16x-8x = 78+22-12 8x = 88 x = 11
-8x -7y
8x - 4x + 7 = 94x + 7 = 94x = 9-74x = 2x = 4/2x = 1/2x = 0.5
To find the product of 8x and 2x, you multiply the coefficients (8 and 2) to get 16, and then multiply the variables (x and x) to get x^2. Therefore, 8x * 2x equals 16x^2.

16x - 8x + 12 = 78 + 22 or simplified to (16x-8x=8x)(78+22=100) 8x + 12 = 100 Simplify some more (Subtract 12 from both sides) 8x = 88 Divide both sides by 8, and x = 11

6x + 9 + 2x = 8x + 9
2x^8 -16x^7 +10x^6 = 2x^6(x^2 - 8x + 5)
16x-8x+12 = 78+22 16x-8x = 78+22-12 8x = 88 x = 11
If you mean: 16x-4y-8x+6y then it is 8x+2y in like terms
