Question

Quizplus · Accepted Answer

To multiply $(x + 3)^2$, you square the first term ($x^2$), multiply the outer and inner terms and double it ($2 \cdot 3x = 6x$), and square the last term ($3^2 = 9$), resulting in $x^2 + 6x + 9$.

Multiply - (x+3)2( x + 3 ) ^ { 2 }(x+3)2

Multiply
- $( x + 3 ) ^ { 2 }$
