Question

Find the solutions to the quadratic equation using the quadratic formula:

x^2 - x = 12

Write the answers as integers.

Answer 1

factoriz it like (x-4)(x+3)

Answer 2

so than you like using discriminant hope you know sormula of ...

Answer 3

formula of

sorry

Answer 4

x+x-x-12=0

Answer 5

so you have learned about discriminant D=b^2 -4ac ?

Answer 6

kinda.. don't understand it..

Answer 7

this mean that you dont learned again ?

Answer 8

I do the whole.
x+x-x-12=0 think

Answer 9

x^2-x-12=0 ... quadratic equation

D = b2 - 4ac = 49
D>0 ... The equation has two distinct real roots

x1 = 4
x2 = -3
P = {4; -3}
