Question

Find the product: (45x2+y)(45x2+y)

Answer 1

Answer:

$2025x^{4} + 90x^{2} y+y^{2}$

Step-by-step explanation

$(45x^{2} +y). (45x^{2} +y)$

=  $(45x^{2} +y)^{2}$

• $(a+b)^{2} = a^{2} +2ab+b^{2}$

=  [$(45x^{2} )^{2} + 2. 45x^{2} .y+ y^{2}$]

• $(a.b)^{m} = a^{m} .b^{m}$
• $(a^{n} ) ^{m} = a^{n.m}$

= $2025x^{4} + 90x^{2} y+y^{2}$
