Question

Multiply the polynomials using the special product formulas.  (x+5)2

maul124uk · Accepted Answer

Product of (x+5)2  (x+5)2=(x+5)(x+5)  using identities  (x+a)(x+b)=x2+(a+b)x+ab  (x+5)(x+5)=x2+(5+5)x+5×5  =x2+10x+25  Step 2  OR  (x+5)2  using identity  (x+y)2=x2+2xy+y2  (x+5)2=x2+2x×5+(5)2  =x2+10x+25  ∴ Polynomial =x2+10x+25
