Factor to find the zeros of the function defined by the quadratic expression. 16x2 − 240x + 896 A) x = 7 or x = 8 B) x = 7 or x = −8 C) x = −7 or x = 8 D) x = −7 or x = −8
Question
Answer:
16x2 − 240x + 896 --->divide all by 1616(x2 - 15x +56)
16{x2- 7x -8x +56x}
16{x(x-7) -8(x-7)}
16(x-8)(x-7)
x1=8/1= 8
x2= 7/1= 7
The answer would be A) x = 7 or x = 8
