Question

4x2-x+1=x-9+2x2 alguem me ajuda nessa equação de 2 grau​

Answer 1

Resposta:

Let's solve your equation step-by-step.

(4)(2)−x+1=x−9+(2)(2)

Step 1: Simplify both sides of the equation.

(4)(2)−x+1=x−9+(2)(2)

8+−x+1=x+−9+4

(−x)+(8+1)=(x)+(−9+4)(Combine Like Terms)

−x+9=x+−5

−x+9=x−5

Step 2: Subtract x from both sides.

−x+9−x=x−5−x

−2x+9=−5

Step 3: Subtract 9 from both sides.

−2x+9−9=−5−9

−2x=−14

Step 4: Divide both sides by -2.

−2x/−2=−14/−2

x=7
