a. 4y2 +8y - 2 = 0 c. 4y2 - 8y + 2 = 0
b. 4y2 +8y + 2 = 0 d. -4y² +8y - 2 = 0
8. What is the value of b if (2x+3)(x-5)=0 is written in the form ax2 + bx + c = 0?
a. -2 c. -7
b. 2 d. 7
9. What are the values of a, b, and c if 3m2 – 6m = 8m + 6m2 – 4 is written in
the form am2 + bm + c = 0?
a. a = -3, b = - 14, c = -4 c. a = -3, b = -14, c = -4
b. a = 3, b = 14, c = -4 d. a = 9, b = 14, c = -4
Solution :
3m² - 6m = 8m + 6m² - 4
3m² - 6m² - 6m - 8m + 4 = 0
-3m² - 14m + 4 = 0
a = -3 , b = -14 , c = 4
Note: Confusing ang choices po. same lang choices ng "a" and "c". wala sa choices yung sagot which is a = -3 , b = -14 , c = 4
