B Getting to the Answer: Set the equation equal to zere, then divide through by 3 on both sides to remove the -coefficient: 3x^2+9x-54=0 x^2+3x-18=0 (x-3)(x+6)=0 x=30r-6 The question asks for the sum of the roots, which is 3t(t)=3. The correct answer is (B)....
Factoring, we get (|x|−8)(|x|+3)=0, so |x|={8,−3}. Since the radicand of the equation can't be negative, the sole solution is |x|=8. Therefore, the x can be 8 or −8. The product is then −8×8=(A) −64.结果一 题目 What is the product of all the...
