Ramses ruled 3 years longer than 7 times as many years as tutankhamen. if x were to equal the number of years tutankhamen ruled, what mathematical expression would tell you how many years ramses ruled?

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer
