Using the order of operations, what should be done first when evaluating this expression? Negative one-half divided by 2 (9 + 3) minus 4 minus three-fourths (8)

0.85% : )

step-by-step explanation:

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative

"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

=

x=0.8898305 is the answer to that equation
