A.) (5x - 12)^2 /
B.) (12 + 5x) (12 - 5x)
C.) (5x + 12) (5x - 12)
D.) (12 - 5x)^2 /

Me solve this problem, and someone clearly explain to me how to solve it.1.) use the value of the discriminant to determine if the given trinomials has 2 real solutions, 1 real solution, or no real solutions.a.  x2  − 4x  − 7 = 0b. 4r2  + 11r  − 3 = 0c. 3m2  + 7 = 0d.  t2  + 2t  + 1 = 0

Simplify. 4+3/7x-2-2/7x a. 2-5/7x b. 6-1/7x c. 2+1/7x d. 6+5/7x

Which of these lines passes through the point (1,-1) and has a slope of -3?
