Answer: If the quadratic equation has real, rational solutions, the quickest way to solve it is often to factorise into the form (px + q)(mx + n), where m, n, p and q are integers. This is especially true where the coefficient of x2 is 1.
Example 1 - Solve x2+7x+12=0
Step-by-step explanation:
that's the only one I remember
Answer:
factoring, using the square roots, completing the square and the quadratic formula.
a) 4x +6
Add up all the sides to calculate perimeter
x = 27
y = 29
1.08×10^11
1.08 times 10 to the power of 11
b )
cube root =
c ) square root
