Question

Pease solve the questions in the picture using the identity.... Stepwise explanation Plzz...

Answer 1

Step-by-step explanation:

$(i) \: \: \: \: \: \: (5x + 11) ^{2} \\ = (5x) ^{2} + 2 \times 5x \times 11 + (11) ^{2} \\ =25x^{2} + 110x + 121 \\ \\ (i) \: \: \: \: \: (x - 8)^{2} \\ = ( {x})^{2} - 2 \times x \times ( - 8) - ( - 8) ^{2} \\ = {x}^{2} + 16x - 64$

Answer 2

Step-by-step explanation:

(I) (5x+11)^2

firstly putting formula on this question

therefore

5x^2 + 2×5x×11 + 11^2

now simplify this equation

25x^2 + 110x + 121

this is the answer of question (I)

now

(ii)(x-8)^2

firstly putting formula on this question

therefore

x^2 - 2× (x) × 8 + 8x^2

now simplify this equation

x^2 - 16 x + 64^x
