You can put this solution on YOUR website! Solve the quadratic equation x^2 + 16x = -64 by factoring.
x^2+16x+64 = 0
(x+8)^2 = 0
x = -8 with multiplicity 2
==================================
Question 4
Solve the quadratic equation m^2+ 2m − 24 = 0 by factoring.
(x+6)(x-4) = 0
x = -6 or x = 4
==================
{-6, 4}
=====================
Question 5
Determine the number of solutions of 2x^2 + 3x = 0.
Factor:
x(2x+3) = 0
x = 0 or x = -3/2
==========================
