Question

the value of "a" for which each one of the roots of x^2-4ax+2a^2-3a+5=0 is greater than 2,are
​

Answer 1

replace x with any variable like y + 2 = x

then from the so formed equation find the value of a for which the value of y will be greater than zero

as the value of a for which y will be greater than zero the value of x will be greater than 2
