Question

Write the equation in standard form. Show Work!

Answer 1

Answer:

1. $2x^2-15x+17=0$

2. $2.4x^2-3.5x-2.2=0$

3. $-4.2x^2+6.8x-2=0$

Step-by-step explanation:

Standard form is written as $ax^2+bx+c=0$. To write each equation in standard from:

• Distribute into any parenthesis
• Move terms across the equal sign with inverse operations
• Combine any like terms

1.

$2(x-3)^2=3x+1\\\\2(x^2-6x+9)=3x+1\\\\2x^2-12x+18=3x+1\\\\2x^2-15x+17=0$

2.

$2.4x^2-3.5x=2.2\\\\2.4x^2-3.5x-2.2=0$

3.

$6.8x - 2 = 4.2x^2\\\\-4.2x^2+6.8x-2=0$
