Second time posting! I need help ASAP (MARKING BRAINLIEST FOR BEST ANSWER) Thanks

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

Which shows one way to determine the factors of 4x3 + x2 – 8x – 2 by grouping?
