2x²+8x=x²-16

2x²-x²+8x+16=0

x²+8x+16=0

D=b²-4ac

=8²-4×1×16

=64-64

=0

x= -b+VD / 2a

=-8+V0 /2

= -8/2

=-4

If Rihanna deposite 1500 rupees in the school fund at 9 p.C.P.A for 2 years, what is the total amount she will get?
S_A_V [24]

Answer: 1770 rupees

Step-by-step explanation:

To solve this, we first calculate the simple interest which will be:

= (P × R × T) / 100

= (1500 × 9% × 2) / 100

= (1500 × 0.09 × 2) / 100

= 270

The total amount tha she'll get will be:

= 1500 + 270

= 1770 rupees

So take

√

9

out of

√

18

. You should have:

√

√

2

But since

we can simplify further to make:
