Multiplying Polynomials Practice

Simplify:
5(3x+2)

• 3x+10
• 15x+10
• 15x-10
• 3x-10

Simplify:
2x ( -2x -3)

• -4x - 3
• x² - 3
• -4x² - 6x
• -4x - 6

(x +2)(x + 3)

• x² + 5x + 6
• x² + x + 6
• x² + 5x + 5
• x² + 6x + 6

(x + 7)(x + 9)

• x² + 63x + 16
• x² + 16x + 63
• x² + 79
• x² + 16x + 2

(x - 5)(x + 1)

• x² - 4x - 5
• x² + 6x - 5
• x² - 5x - 4
• x² - 4x - 4

(x - 4)(x - 6)

• x² -10x + 24
• x² - 10x - 24
• x² +10x + 24
• x² + 10x - 24

Multiply  7x²y³ (2x⁴y⁵+6xy³)

• 14x⁸y¹⁵+42x²y⁹
• 9x⁶y⁸+13x³y⁶
• 14x⁶y⁸+42x³y⁶
• 14x⁶y⁸+42x²y⁶

Find the sum.
(2x² + 5x - 7) + ( 3 - 4x² + 6x)

• 2x² + 3x +1
• -2x² - 11x -4
• 2x² + 5x -7
• -2x² + 11x -4

Find the difference. 
(3- 2x + 2x²) - (4x -5 +3x²)

• x_² + 6x + 8
• 2x² + 5x - 7
• -x² -6x + 8
• -2x² + 11x - 4

(x + 5)² 

Hint: try (x + 5)(x + 5)

• x² + 25
• x² + 10x + 25
• x² + 10 x + 10
• x² + 10
