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

\left[\begin{array}{ccc}22&18\end{array}\right]\times\left[\begin{array}{cccc}5&18&32&40\\25&40&38&12\end{array}\right]\\\\=\left[\begin{array}{cccc}22\cdot5+18\cdot25&22\cdot18+18\cdot40&22\cdot32+18\cdot38&22\cdot40+18\cdot12\end{array}\right]\\\\=\left[\begin{array}{cccc}560&1116&1388&1096\end{array}\right]

second question:

January: 32 · 22 + 38 · 18 = 704 + 684 = 1388

December: 18 · 22 + 40 · 18 = 396 + 720 = 1116

1388 - 1116 = 272
