Factor and solve the problems in the photo ……….. pleaseeeee help i haven’t done algebra in 2 years
vladimir1956 [14]

Answer:

30. 2x²-x-1=0

or, 2x²-2x+x-1=0

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

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

so, x-1 = 0 or, x = 1

and 2x+1 = 0 or, 2x = -1 or, x = -1/2

so, x = 1 and 1/2

31. 3x²-14x=5

or, 3x²-14x-5=0

or, 3x²-15x+x-5=0

or, 3x(x-5)+1(x-5)=0

or, (x-5)(3x+1)=0

so, x-5=0 or, x=5

and 3x+1=0 or, 3x=-1 or, x=-1/3

so, x = 5 and -1/3

A system of equations is shown below.
Alja [10]

You can use the process elimination to solve. In other words, subtract or add the equations like normal.

5x + 2y = -15

+ 2x - 2y = -6

Because there is a 2y and -2y, we can add both equations to eliminate the y so that we can figure out what x is:

5x + 2x = 7x

2y + (-2y) = 0

-15 + (-6) = -21

We now have 7x = -21

Divide all by 7 to get x = -3

Plug in -3 to any of the two equations. I will use the second equation:

2(-3) - 2y = -6

-6 - 2y = -6

-2y = 0

y = 0

This means that the solution to the system of equations is (-3, 0) in the form of (x, y).
