Q.4 (b) Identify terms which contain \( y^2 \)and give the coefficients of\( y^2.\)
(i) \( 8 – xy^2 \)
(ii) \( 5y^2 + 7x \)
(iii) \(2x^2y – 15xy^2 + 7y^2 \)

(i) Expression: \( 8 – xy^2 \)
Term : \(-xy^2\)
Coefficient of\( y^2 =- x \)
(ii) Expression: \( 5y^2 + 7x \)
Term : \(5y^2\)
Coefficient of\( y^2 = 5 \)
(iii) Expression: \(2x^2y – 15xy^2 + 7y^2 \)
Term : \( – 15xy^2 , 7y^2 \)
Coefficient of\( y^2 = -15x , 7 \)
