What is the positive solution of x^2 – 36 = 5x
2 answers:
Answer: 9
Step-by-step explanation:
The equation x^2 - 36 = 5x is a quadratic equation and can be solved thus: x^2 - 36 = 5x x^2 - 5x - 36 = 0 x^2 + 4x - 9x - 36 = 0 x(x + 4) - 9(x + 4) = 0 (x - 9)(x + 4) = 0 x - 9 = 0 or x + 4 = 0 x = 9 or x = -4 Therefore, the positive solution of x^2 - 36 = 5x? is 9.
Answer:
x=9, x=-4(rejected)
Step-by-step explanation:
rearrange the equation given then equate it to 0.
do the factorisation cross method. since the question asking for positive value then automatically the negative value will be rejected.

Step-by-step explanation:
3x²+3x-6
=3(x²+x-2)
=3(x²+2x-x-2)
=3[x(x+2)-1(x+2)]
=3(x+2)(x-1)
Point slope: y - y1 = m(x - x1) Plug those in Solution: y + 8 = 4(x - 2)
