You select two marbles (without replacement) from a bag containing eight red marbles (denote by R), five blue marbles (denote by B), and one yellow marble (denote by Y). You record the color of each marble.

squares, rhombus, rectangles

"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

i think the answer is b x = 1, y = 35/2
