solve: x^2-2x-48=0

Question

Step by step to solve these problems:  1. x^2 - 2x - 48 = 0

                                                              2. 4x + 4y = 0

                                                                 4x + y = -24

                                                              3. x^2 -7x + 0 = 0

Answer 1

x^2 -2x-48=0

quadratik equashun giv roots=8 & -6

or (x-8)*(x+6)=0

Answer 2

x^2 - 2x - 48 = 0

(x - 8)(x + 6) = 0

x = 8, -6

.

4x + 4y = 0

4x + y = -24

multiply the bottom equation by -1 on both sides

4x + 4y = 0

-4x - y = 24

add the equations together

0x + 3y = 24

3y = 24

y = 8

4x + y = -24

4x + 8 = -24

4x = -32

x = -8

Answer:  x = -8, y = 8

.

x^2 -7x + 0 = 0

x^2 - 7x = 0

x(x - 7) = 0

x = 0, 7
