Question

solve (7x^2+14x)^2 using suitable identity. ​

Answer 1

Answer:

49x⁴ + 196x³ + 196x².

Step-by-step explanation:

By using (a + b)² = a² + 2ab + b²,

(7x² + 14x)²

(7x²)² + 2(7x²)(14x) + (14x)²

49x⁴ + 196x³ + 196x².

Answer 2

Step-by-step explanation:

the identity used here will be(a+b)^2=a^2+b^2+2ab

={(7x^2)^2+(14x^2)^2+2(7x^2)(14x^2)

={7x^4+14x^4+14x^2×14x^2}

={7x^4+14x^4+196x^4}

=217x^4
