Question

how would this be solved by graphing, factoring, the quadratic formula, and by completing the square. x2–3x–4 = 0

Answer 1

i'm assuming the (x2) is supposed to be \[x ^{2}\]the solution will be found by factoring.

Answer 2

this is because 2 numbers multiplied together will give you an answer of (-4). and those same numbers added together would give you (-3).

Answer 3

(x-_)(x+_)=0
can you find the two numbers?

Answer 4

-4 and 1? @montelbaun
