2x^2+3x=(2x-1)(x+1)
Pls do explain

You could solve this problem by either: Factoring or by using the Quadratic Formula.

SOLVING BY FACTORING STEPS

STEP 1: Move (2x−1)(x+1) to the left side of the equation by subtracting it from both sides.

STEP 2: Simplify 2x^2+3x−(2x−1)(x+1).

STEP 3: Simplify each term.

STEP 4: Simplify by adding terms.

STEP 5: Subtract 1 from both sides of the equation.

STEP 6: Divide each term by 2 and simplify.

SOLVE BY USING THE QUADRATIC FORMULA STEPS

STEP 1: Move all terms to the left side of the equation and simplify.

STEP 2: Subtract 1 from both sides of the equation.

STEP 3: Divide each term by 2 and simplify.

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
