Answer:
1. A) -6x^2+11x-4
2. C) (3x+7y)(3x-7y)
3. A) (x+7)(x+2)
4. not sure. D. 2 nonreal solutions
5. C) 11
Step-by-step explanation:
1. Multiply them together one by one. First multiply -3x by 2x-1 and then 4 times 2x-1.
2. The factored equation had to have one positive sign and one negative so when you got plus or negative 21xy, it will cancel out by a 21xy of the opposite sign
3. each parenthesis needs to have x because the equation has x^2. And the remaining numbers have to be numbers that sum up to 5. and play with the signs till you figure out the equation.
4. You have to do the discriminant thing that's like (-b±√b²-4ac)/2a and the degree of the equation shows how many solutions there is going to be.
5. Just try out all your options till you find the right answer.
