Question

Find the zeroes of the polynomail ​

Answer 1

Answer:

49x²-64=0

49x²=64

x²=64/49

x= +8/7 or-8/7

Answer 2

Answer:

$49 {x}^{2} - 64 \\ =( 7x) {}^{2} - (8) {}^{2} \\ we \: know \: that \: \\ x {}^{2} - y {}^{2} = (x + y)(x - y) \\ so \: (7x) {}^{2} - (8) {}^{2} = (7x + 8)(7x - 8) \\ and \: root \: (zeroes) \: = \frac{8}{7} \: \: and \: \: \frac{ - 8}{7} \: \: ans$
