To find the sum of the two expressions, we can simply combine like terms.
The first expression is -3x + 9.
The second expression is 7x^2 - 2x + 1.
To combine the terms, we add the coefficients of the like terms.
The x term in the first expression is -3x, and the x term in the second expression is -2x. The combined x term would be -3x - 2x = -5x.
So far, the sum is -5x.
Next, we add the constant terms. In the first expression, we have the constant term 9. In the second expression, we have the constant term 1. The combined constant term would be 9 + 1 = 10.
Now, the sum of the two expressions is -5x + 10.
The first expression is -3x + 9.
The second expression is 7x^2 - 2x + 1.
To combine the terms, we add the coefficients of the like terms.
The x term in the first expression is -3x, and the x term in the second expression is -2x. The combined x term would be -3x - 2x = -5x.
So far, the sum is -5x.
Next, we add the constant terms. In the first expression, we have the constant term 9. In the second expression, we have the constant term 1. The combined constant term would be 9 + 1 = 10.
