Patel is solving 8x2 + 16x + 3 = 0. which steps could he use to solve the quadratic equation? check all that apply.

1.    A quadratic equation has the general formula expressed as:

ax^2 + bx - c = 0

This equation can be solved by the quadratic formula which is expressed as:

x = ( -b (+ or -) √(b^2 - 4ac) / 2a

From the given equation,

a = 8
b = 16
c = 3

x = ( -16 (+ or -) √(16^2 - 4(8)(3)) / 2(8)
x1 = -0.21
x2 = -1.79

Step-by-step explanation:

Given that Patel is solving the quadratic equation

This can be done by factorisation or using formula or completion of squares method.

Since factorization does not seem to be possible let us resort to completion of squares method.

use the power rule  

( a b ) n = a n b n

to distribute the exponent.

apply the product rule to  

3 x 2 y 3 . ( 3 x 2 ) 2 ( y 3 ) 2

apply the product rule to  

3 x 2 . 3 2 ( x 2 ) 2 ( y 3 ) 2

raise  

3

to the power of  

2 . 9 ( x 2 ) 2 ( y 3 ) 2 multiply the exponents in   ( x 2 ) 2

.

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 2 ⋅ 2 ( y 3 ) 2

multiply  

2   by   2 . 9 x 4 ( y 3 ) 2

multiply the exponents in  

( y 3 ) 2 .

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 4 y 3

⋅

2

multiply  

3   by   2 . 9 x 4 y 6
