mutiply the numerators together
(7x)(x)= 7x^ 2
mutiply the denominators together
(x-4)(x+7)
(x)(x)(7)(x)= x^2+7x
(-4)(x)(-4)(7)= -4x-28
x^2+7x-4x-28
x^2+3x-28
Answer:
7x^2/x^ 2+3x-28
Answer:
Step-by-step explanation:
All those words, when the math is so much clearer!
x = (9±√(9^2-4*1*5))/2 = (9±√101)/2
3, 6, 9, 12, 15
5, 10, 15
