Question

Factorize the following by splitting the middle term
A a²+46a+25
B m-26m+133
C m²-3m-70
D 3a² - 5b+2

Answer 1

Step-by-step explanation:

m²-10m+7m-70

m(m-10)+7(m-10)

(m+7)(m-10)

3a²-5a+2

3a²-3a-2a+2

3a(a-1)-2(a-1)

(3a-2)(a-1)

m²-26m+133

m²-19m-7m+133

m(m-19)-7(m-19)

(m-19)(m-7)

i guess first one is incorrect

may be the statement is a²+26a+25

a²+25a+a+25

a(a+25)+1(a+25)

(a+1)(a+25)
