Question

Solve the equation: p2 - 4p + 4 = 0.​

Answer 1

Perfect square trinomial

$\boxed{ a^2 \pm 2ab+b^2 = (a \pm b)^2 }$

Using the perfect square trinomial

$p^2 - 4p + 4 = 0$

$p^2 - 2(2p) + (2)^2 = 0$

$(p-2)^2 = 0$

$(p-2) = 0$

$p = 2$

Answer 2

$\huge\text{Hey there!}$

$\bold{p^2-4p+4=0}$

$\text{FACTOR the LEFT side of your equation}\\\bold{(p-2)(p-2)=0}$

$\text{SET each of your FACTORS TO EQUAL to 0}\\\bold{p-2=0\ or\ p-2=0}$

$\text{SIMPLIFY the equations\ above and you will have your answer}$

$\boxed{\boxed{\bold{Answer: \large\text{\bf{p = 2}}}}}\huge\checkmark$

$\textsf{Good luck on your assignment and enjoy your day!}$
