If you have any comments or feedback for Gill, please share them below. Therefore, the solution is, Question 2: Solve the inequality x^2-3x>0. Since the inequality is now x^2+5x+4\geq0, the question becomes: when does the graph go above zero on the y-axis? come with answers. To solve this quadratic inequality we first have to rearrange by adding 4 4 to both sides so that x^2+5x+4\geq0 x2 + 5x + 4 0 Observing that 1\times4=4 1 4 = 4 and 1+4=5 1 + 4 = 5, we can factorise this to be (x+1) (x+4)\geq0 (x + 1)(x+ 4) 0 Using this information, we can sketch the graph of y=x^2=5x+4 y = x2 = 5x + 4. The inequality in the question is x^2-10x+16<0, so the question is: when does the graph go below zero?

This can be expressed as, Here we have to divide both sides of the equation by 2 so that x^2 \gt 9, The values that satisfy this inequality are. Solving Quadratics using Factorisation - Corbettmaths - YouTube As with linear inequalities, we can rearrange them to find solutions similar to if they were equations. Before going further, you should be familiar with the following topics: When solving quadratic inequalities it is important to remember there are two roots. Quadratic Inequalities Video - Corbettmaths Quadratic Inequalities - Corbettmaths - YouTube So, we will factorise this quadratic, and then use what would be the solutions to help us plot the graph. I hope you find it useful. Inequalities are the relationships between two expressions which are not equal to one another. Therefore, the solution is, Question 5: Solve the inequality x^2-5x+24<5x+8, \begin{aligned}x^2-5x+24&<5x+8 \\ x^2-10x+16&<0 \\ (x-8)(x-2)&<0\end{aligned}, Hence x can take any value between 2Quadratic Inequalities Practice Questions - Corbettmaths It is important to remember that there are two solutions to such inequalities. Observing that (-2)\times(-3)=6 and (-2)+(-3)=-5, we get that inequality can be written as, \begin{aligned}x^2-5x+6&\leq0 \\(x-2)(x-3)&\leq0\end{aligned}, So, the roots of this quadratic would be x=2 and x=3, therefore the graph looks like.

For more ideas on how to use these types of activities (including twists!) We can see that it goes below zero between the values x is greater than 2 and x is less than 8. The inequality is satisfied for values of x that fall strictly between -1 and 3, so we write the solution as, To solve this quadratic inequality we first have to rearrange by adding 4 to both sides so that, Observing that 1\times4=4 and 1+4=5, we can factorise this to be (x+1)(x+4)\geq0.
