Answer : 2x² - 7x - 30
Step-by-step explanation: Multiply the brackets out (first x * 2x then x * 5) (second -6 * 2x then -6 * 5) which will give you 2x² + 5x - 12x - 30. Take away 12 from 5 which gave you the negative 7.
Answer:
4cm, 11cm, 21cm
Step-by-step explanation:
4(x + 1)(x + 11)
4(x ^ 2 + 12x + 44)
x ^ 2 + 12x + 11 = 231
x ^ 2 + 12x + 11 - 231 = 0
x ^ 2 + 12x - 220 = 0
(x - 10)(x + 22) = 0
x = 10 and x = - 22
4cm , 11cm , 21cm
