If f(x)= |4x - 1|, find the value of x if(x) = 7
vaieri [72.5K]
F(x) = | 4x - 1 | .....when f(x) = 7
7 = | 4x - 1 |

4x - 1 = 7               -(4x - 1) = 7
4x = 7 + 1               -4x + 1 = 7
4x = 8                      -4x = 7 - 1
x = 8/4                     -4x = 6
x = 2                          x = -6/4
                                  x = - 3/2

solutions are x = -3/2, 2

Find the GCF of each expression. Then factor the expression.
GaryK [48]
For finding GCF, just find the least number among them.
For example: 
a.) 6x^2 - 9 find what number that can be divided to 6. In this case, it is 2 and 3. 
You can't divide 9 by 2 so the answer in this equation would be 3.

b.) 2a^ 2 + 22a + 60 I's just the same method to use. In this case, we will use 2a^2. The factors that can be divided to 2 is (2,1). So we will choose 2 because it is the GCF of 2 and the equation is divisible by 2.
