Question

The roots of the equation 4x-3*2x+2+32=0 would include-

Answer 1

(4x-3)(2x+2)+32=0

8x^2+8x-6x-6+32=0

8x^2+2x+26=0

(÷ by 2)

4x^2+x+13=0

it can't be factorized

using formula method

a=4,b=1,c=13

∆=b^2-4ac

=(1)(1)-4(4)(13)

=1-16*13

=1-208

=-207

roots of eqn are not real

Answer 2

Answer:

2,3

Step-by-step explanation:

Given equation is 4^2x - 3.2^x * 2^2 + 32 = 0

2^2x - 12.2^x + 32 = 0

let y = 2^x

y - 12y + 32 = 0  

solve y=8 or y=4

2^x = 8  

x = 3

and 2^x = 4  

x = 2

2 and 3
