Question

solve this x(2x+3)=x²+1​

Answer 1

Step-by-step explanation:

First apply distributive property.nextmove terms to the left side .next distribute.nect combine like terms.then multiply by 1 use quadratic formula and simplifynow separate the equation.

Answer 2

Answer:

x=(-3-sqrt(13))/2=-3.303

x=(-3+sqrt(13))/2=0.303

Step-by-step explanation:Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :  x*(2*x+3)-(x^2+1)=0

x • (2x + 3) -  (x2 + 1)  = 0  Factoring  x2+3x-1

The first term is,  x2  its coefficient is  1 .

The middle term is,  +3x  its coefficient is  3 .

The last term, "the constant", is  -1

Step-1 : Multiply the coefficient of the first term by the constant   1 • -1 = -1

Step-2 : Find two factors of  -1  whose sum equals the coefficient of the middle term, which is   3 .      -1    +    1    =    0
