Answer:

D)   \frac{4x-3} {x+6}

Step-by-step explanation:

First we have to factorize and then cancel the like terms.

Given,

\frac{4x^2-7x+3} {x^{2}+5x-6}\\=\frac{4x^2-3x-4x+3} {x^{2}+6x-x-6}\\=\frac{x(4x-3)-1(4x-3)} {x(x+6)-1(x+6)}\\=\frac{(4x-3)(x-1)} {(x+6)(x-1)}

Now, we got the like term  (x-1).

Canceling this like term we get

\frac{(4x-3)(x-1)} {(x+6)(x-1)}=\frac{4x-3} {x+6}

Find all the complex roots of the equation x4 − 16 = 0.
TiliK225 [7]

Answer:

4+16=0

4=−16=162

2=±4

Case 1  2=+4

=±2√

√=±(12√+12√)

=±2‾√+2‾√

Case 2  2=−4=43

=±23/2=±2()1/2

∵√=±(12√+12√)

=±(2‾√+2‾√)

So in all,

=2‾√+2‾√

=−2‾√+2‾√

=2‾√−2‾√

=−2‾√−2‾√

Let  √=+

Squaring both sides, we have

=(+)2

0+1=2−2+2⟹

2−2=0(1)

2=1

=12

Plugging in  (1)  … ⟹

2−1(2)2=0

4=14

2=12

∴=±12‾√

∴=±12‾√

∴√=+=±(12+12)

This can also be shown as below

√=12+12

Or

√=−12−12 \
