Answer:

Since we know that

(a+b)

+2ab+b

(a−b)

−2ab+b

Now,

(i)

(x+3y)

+2×x×3y+(3y)

+6xy+9y

(ii)

(2x−5y)

=(2x)

−2×2x×5y+(5y)

=4x

−20xy+25y

(iii)

(a+

)

+2×a×

)

+1+

(iv)

(2a−1a)=(1a)

(1a)

=1a

Answer:

By comparing the ratios of sides in similar triangles ΔABC and ΔADB,we can say that $x^{2} =pz$

Step-by-step explanation:

Given that ∠ABC=∠ADC, AD=p and DC=q.

Let us take compare Δ ABC and Δ ADB in the attached file , ∠A is common in both triangles

and given ∠ABC=∠ADB=90°

Hence using AA postulate, ΔABC ≈ ΔADB.

Now we will equate respective side ratios in both triangles.

$\frac{AB}{AC}= \frac{AD}{AB}=\frac{BD}{BC}$

Since we don't know BD , BC let us take first equality and plugin the variables given in respective sides.

$\frac{x}{z}= \frac{p}{x}$

Cross multiply

$x^{2}=pz$

Hence proved.
