Use ax^2 + bx + c = 0
ac = -8
b = 2
The factors are 4 and -2.
Plug them into the equation:
x^2 + 4x - 2x - 8
Then factorise it:
x ( x + 4) - 2 (x + 4)
so m = 4
(x + 4)^2
Answer:
Step-by-step explanation:
x + y = 27
We know that there are 5 less girls that boys, so:
x + (x-5) = 27
x + x - 5 = 27
Solve for x:
2x - 5 = 27
2x = 32
x = 16 boys
y = 11 girls
