Answer:
x = 10
Step-by-step explanation:
The solution that had the same solution as the system below is B , the answer is B
Answer:
Factorising the equation into brackets can help you identify where the x-intercepts are (where the function cuts the x-axis)
Step-by-step explanation:
When you factorise the equation it would look something like this:
(x + a)(x + b) = 0
This also means:
x + a = 0 and x + b = 0
x = -a and x = -b
Example:
Find where the function y = 2x² + 8x + 6 cuts the x-axis
Factorise the 2 out (highest common factor)
x² + 4x + 3 = 0
(x + 1)(x + 3) = 0
x = -1 or -3
