2x² < x+3, 2x²- x - 3 < 0, (2x - 3) (x + 1) < 0, Positive quadratic. Roots: x = -1 and x = 3/2, Therefore, x takes values greater than -1 and less tha...

Firstly, multiply the whole equation by (4 - a) to cancel out the denominator, so the equation becomes: p(4 - a) = (3a + 5). Then expand the brackets: 4p - ap = 3a +5. Then rearrange the equation to: 4p -...

First start by considering the x⁰ coefficient which is -3. These include ±3 and ±1. Substituting x=1 into the polynomial produces an answer of 0 which shows that x=1 is a factor of the polynomi...

To understand the question, we have to know what a third is. 1 is made up of three thirds (3/3 presented in a fraction), so in order to obtain 9 we must multiply it by 3. The answer is 27.

Motion is a topic in physics that is sometimes hard to understand. When we talk about motion we think about acceleration, velocity, time and displacement. In the case of projectile motion, we usually disc...
