21x + 9 = 180 21x = 180 - 9 21x = 171 x = 171/21 x = 8.143
To factor 4x^2 - 21x + 5, we look for two binomials in the form (Ax + B)(Cx + D) that multiply to give 4x^2 - 21x + 5. We can determine the values of A, B, C, and D by examining the factors of 4 and 5. The factored form is then (4x - 1)(x - 5).
If: 9x = 21x-3 Then: x = 1/4 or 0.25
