Question

Expand and simplify: ${{\left( a+b \right)}^{2}}$ ${{\left( 2a-b \right)}^{2}}$ ${{\left( 3x+1 \right)}^{2}}$ Factorise completely: ${{a}^{2}}+2ab+{{b}^{2}}$ $4{{a}^{2}}-4ab+{{b}^{2}}$ $9{{x}^{2}}+6x+1$

Accepted Answer

(a) a² + 2ab + b²; (b) 4a² - 4ab + b²; (c) 9x² + 6x + 1; (d) (a+b)²; (e) (2a-b)²; (f) (3x+1)²
