GCSE Secondary Maths Age 13-17 - Algebra: Algebra - Explained

The video tutorial covers factorizing quadratic equations, solving linear inequalities, and finding integer solutions within a specified range. It emphasizes the importance of understanding procedures and accurately presenting final answers to avoid losing marks.

What are the correct factor pairs for the quadratic expression y^2 + 7y + 6?

• (y - 6)(y - 1)

• (y - 3)(y - 2)

• (y + 6)(y + 1)

• (y + 3)(y + 2)

When solving the inequality 6x + 4 > x + 17, what is the correct final inequality?

• x = 13/5

• x < 13/5

• x >= 13/5

• x > 13/5

What is the first step in solving the inequality 6x + 4 > x + 17?

• Add x to both sides

• Subtract x from both sides

• Multiply both sides by 5

• Divide both sides by 6

For the inequality -5 < 2N <= 6, what is the range of integer values for N?

• -2, -1, 0, 1, 2

• -2, -1, 0, 1, 2, 3

• -3, -2, -1, 0, 1, 2

• -1, 0, 1, 2, 3, 4

What is the result of dividing the inequality -5 < 2N <= 6 by 2?

• -5 < N < 3

• -5/2 < N < 3

• -5 < N <= 3

• -5/2 < N <= 3
