To find the sum of the two expressions \( 7 x^{2}-3 x+2 \) and \( 8 x^{2}+9 x-3 \), you simply add the corresponding coefficients of each term: 1. For \( x^2 \) terms: \( 7x^2 + 8x^2 = 15x^2 \) 2. For \( x \) terms: \( -3x + 9x = 6x \) 3. For the constant terms: \( 2 - 3 = -1 \) Now, combine these results: \[ 15x^2 + 6x - 1 \] So, the sum of the two expressions is \( 15x^2 + 6x - 1 \).
