Given the polynomial function: f(x)=t(x+2)^2(x-5)(x+3), what is the degree of f(x)?

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

Solve the inequality and graph 6j - 7 < 5

What adds to be the bottom number but also multiplies to be the top number with 8 on the bottom and 15 on top
