What is a factor of 6x2 + x - 7?
Solution:
The factors of any quadratic equation can be found by factorization method
The factorization means multiply the coefficient of x2 with constant term
⇒ x2 coefficient is 6 and constant term is -7,on multiplying -42.
Now need to find the factors of - 42 such that the sum is 1
⇒ The factors are +7 and -6 so that the product is - 42 and sum is +1
According to this x term needs to be rearranged.
⇒ 6x2 +7x − 6x - 7 = 0
Separating common terms as underlined
⇒x ( 6x + 7) - 1 ( 6x + 7) = 0
Again 6x + 7 is common term and on separating
⇒ (x - 1) (6x + 7) = 0
⇒ x = 1 and x = -7 / 6.
Hence, the values of x are 1 and -7 / 6.
What is a factor of 6x2 + x - 7 ?
Summary:
The factors of 6x2 + x - 7 are 1 and (-7 / 6)
