Question

23x + 26 = (3x + 4)2
$23x + 26 = {3x}^{2} + {4}^{2} \:$ then find the value of x
​

Answer 1

Answer:

x=-2,5/3

Step-by-step explanation:

23x+26=(3x+4)²

=>23x+26=3x²+16+24x

shifting all on one side,

=>3x²+x-10=0

=>3x²+6x-5x-10=0

=>3x(x+2)-5(x+5)=0

=>(x+2)(3x-5)=0

=>x =-2, 5/3.

good luck
