- 16x - 4
Step 1:
Multiply the lead coefficient times the constant ( a
c), this will
now become the new c..
Step 2:
Factor like other trinomials.
Step 3:
Divide the constant terms of the factors by the lead coefficient
Step 4:
Simplify the fractions if possible
.
Step 5:
Rewrite by moving all remaining denominators back to the lead
coefficient position..
Step 5:
Solve using zero product rule.
