Question

Find the zeroes of the following and also verify the relationship
between the zeroes and co-
4x² -12x + 9
11) x² - 5x+6
1) x² - 15​

Answer 1

Step-by-step explanation:

4x² -12x + 9

=(2x)²-2.2x.3+3²

=(2x-3)²

= (2x-3)(2x-3)

(2x-3)=0 ,(2x-3)=0

x=3/2 ,x=3/2

x² - 5x+6

=x²-2x-3x+6

=x(x-2)-3(x-2)

=(x-2)(x-3)

x-2=0 or. x-3=0

x=2 x=3

x²-15

x²=15

x=√15

x=±√15

x=√15,-√15
