Answer:
Step-by-step explanation:
You have to use the discriminant for this. If the quadratic is
, then
a = -4, b = -3, and c = 7. The formula for finding the discriminant is
which comes from the quadratic formula, but without the square root sign. Filling in:
which simplifies down to
D = 9 + 112 so
D = 121. This is a perfect square, so the solutions will be 2 real. Just so you know, you will NEVER have a solution like the one offered in the third choice down. If you have one imaginary root, you will ALWAYS have a second by the conjugate rule.
Answer: 26/52
Step-by-step explanation:
(3x + 2y)^2
Use the FOIL method (first, outside, inside, last)
(3x + 2y) (3x +2y)
9x^2 +6xy +6xy +4y
9x^2 + 12xy + 4y is your answer.
Answer:
D. rectangle with a width of 7 cm and a length of 8 cm
Step-by-step explanation:
If you multiply 7 and 8 you get 56, which is the least area in all of these figures.
