Question

Evaluate : (35)2

( Use of identity is compulsory)​

Answer 1

Answer:

Practice the questions given in the worksheet on the product of two binomials whose first terms are same and second terms are different.

See the identities to find the products of two binomials using the formulas.

1. Use the formula (x + a) (x + b) = x2 + x(a + b) + ab to identity to find the following products.

(i) (x + 5) (x + 6)                                

(ii) (x + 7) (x + 10)            

(iii) (x + 9) (x + 8)                              

(iv) (x + 3) (x + 8)

Answer 2

Step-by-step explanation:

(30+5)^2

=(30)^2+2×30×5+(5)^2 ((a+b)^2=a^2+2ab+b^2)

=900+300+25

=1225(ans)
