Question

QNO5If we factorize 4x2 – 12x + 9 = 0, then value of x are
a)3/2,3/2
b)-3/2,+3/2
c)-3/2,-3/2
d)None of these​

Answer 1

Step-by-step explanation:

Given,

(4x²-12x+9)=0

To find,

The value of x.

Solution

The given expression,(4x²-12x+9) is in the form of a²-2ab+b² i.e (a+b)².

BTP

4x²-12x+9 = 0

(2x)²-2*2x*3+(3)² = 0

(2x-3)² = 0

2x-3 = 0

=> x =

$+ \frac{3}{2}$

or

$- \frac{3}{2}$

so the correct option is b. please mark my answer as the brainiest
