The GCF (Greatest Common Factor) of the given quadratic equation is 4x. Factoring out the GCF, we get:
4x(21x + 4) = 0
Setting each factor equal to zero, we have:
4x = 0 or 21x + 4 = 0
Solving for x in each equation, we find:
x = 0 or 21x = -4
x = -4/21
Therefore, the solutions to the quadratic equation 84x^2 + 16x = 0 are x = 0 and x = -4/21.
Solve the quadratic equation 84x2+16x=0
by factoring out the GCF.
