Which explains how to show that u
is a root of 9.x2 + 48x + 64 = 0?
Substitute 2 =
back into 9x² + 480 + 64 = 0 and simplify to show the values of a and cremain perfect squares.
O Graph 9x2 + 48x + 64 = 0 to show that the parabola's vertex is just above the value x =
CO100
O Graph 9x2 + 48x + 64 = 0 to show that x = - is where the parabola crosses the y-axis.
O Substitute 2 =
back into 9x2 + 48x + 64 = 0 and simplify to show that a true statement results.
