Answer:
Factor by grouping. For a polynomial of the form ax2+bx+c a x 2 + b x + c , rewrite the middle term as a sum of two terms whose product is a⋅c=2⋅15=30 a ⋅ c = 2 ⋅ 15 = 30 and whose sum is b=−11 b = - 11 .
Step-by-step explanation:
Answer:
2 (2x – 5) (x – 3)
Step-by-step explanation:
4x² – 22x + 30
First, factor out a 2:
2 (2x² – 11x + 15)
Use AC method to factor.
2 × 15 = 30
Factors of 30 that add up to -11 are -5 and -6.
Divide by a and reduce: -5/2, -6/2 = -3/1
The factors are 2x – 5 and x – 3.
2 (2x – 5) (x – 3)
