What are the solutions to the equation x2 +3x-4=0

Mathematics

x^{2} +3x-4=0

You wan't to get it into a format of (x+a)(x+b)=0
where a+b = 3 (the one from the 3x)
and where a*b= -4 (from the last -4)

(x+4)(x-1)=0
See how 4+(-1) = 3 and (4)(-1) = -4

now find what values of x would make the equation equal 0
x=-4
(-4+4)(-4-1) = (0)(-5) = 0

x=1
(1+4)(1-1) = (5)(0) = 0

Find the coordinates of the image after a translation of the figure below using (x, y) (x + 3, y + 2).
vekshin1
You have not provided the coordinates of the original points, therefore, I cannot give exact answers.
However, I can help you with the concept.

We are given that the translation rule here is:
(x,y) ................> (x+3 , y+2)

This means that:
x coordinate of the translated point can be obtained by adding 3 to the x coordinate of the original point
y coordinate of the translated point can be obtained by adding 2 to the y coordinate of the original point

Examples:
point (2,3) after translation would become (2+3 , 3+2) which is (5,5)
point (-1,0) after translation would become (-1+3 , 0+2) which is (2,2)

Hope this helps :)
