the first one is already factored, so how come you are stuck on it ?
2nd:
get the equation = 0
then it factors quite easily
4a^2 - 11a + 6 = 0 and 9r^r - 30r + 21 = -4
have you not been taught some kind of a method to factor these kind of trinomials?
A common method these days is "decomposition"
Use factoring and the zero-product property to solve the following problems:
z(z - 1)(z + 3) = 0
x^2 - x - 10 = 2
4a^ - 11a + 6 = 0
9r^r - 30r + 21 = -4
Please show work. Thank you so much!
