Write an equation that models this situation

Kristy wants to make Valentines, each decorated with 4 inches of lace, for 7 of her friends. How much inches of lace (x) does Kristy need to make the cards

Xto the second power plus 14x plus 48. what are the factors? we are doing factoring trinomials with a=1

Polynomial that can be factored as (3x-4)(3x+4)

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
