Question

4x^2-12x=A×B,Where A is ___and B is___​

Answer 1

Answer:

Hi there!

According to given condtn. :-

4x² - 12x + k = (a - b)² = a² - 2ab + b²

Here,

♦

a² = 4

[ Squaring botg sides. ]

a = √4 = 2

♦

2ab = -12

2(2)b = -12

b = -12 / 4

b = 3

Finally,

♦ b² = k

(3)² = k

k = 9

Hence, The required answer is :-

Numerical value of k = 9
