Choose the correct sum of the polynomials (3x3 − 5x − 8) + (5x3 + 7x + 3). 8x3 + 2x + 5 2x3 − 12x − 11 2x3 + 12x − 5 8x3 + 2x − 5

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629

there are no choices to this, can you give us some choices so that i can answer it
