Show that (x+y)² − (x −y)² = 4xy for all real numbers x and y.

nata0808 [166]

To show: (x+y)² − (x −y)² = 4xy

Using difference of square identity:

$a^2-b^2=(a-b)(a+b)$

Taking left side

$\Rightarrow (x+y)^2-(x-y)^2$

$a\rightarrow x+y$

$b\rightarrow x-y$

$\Rightarrow (x+y+x-y)(x+y-x+y)$

$\Rightarrow (2x)(2y)$

$\Rightarrow 4xy$

hence proved

$(x+y)^2-(x-y)^2=4xy$

Solve for xx. Round to the nearest tenth if necessary.

Kazeer [188]

Answer:

x = 37.5

Step-by-step explanation:

By Basic Proportionality Theorem:

$\frac{x}{20} = \frac{46 - 16}{16} \\ \\ \frac{x}{20} = \frac{30}{16} \\ \\ x = \frac{20 \times 30}{16} \\ \\ x = \frac{600}{16} \\ \\ x = 37.5$
