Question

As solve using identity suitable identity 3 X + 4 y whole square

Answer 1

Answer:

Step-by-step explanation:

(3X+4Y)²

SOLVE IT USING IDENTITY

(a+b)²= a² +2ab +b²

Where a=3

b=4

Your answer should be 44

Answer 2

Answer:

$9x^{2} +16y^{2} +24xy$

Step-by-step explanation:

We know that $(a+b)^{2}= a^{2}+b^{2}+2ab$

Hence, by substituting a = 3x and b = 4y, we get

$(3x+4y)^{2}$ = $9x^{2} +16y^{2} +24xy$

Hope you understood
