Question

factorize b^2+7b-30​

Answer 1

so we can factorise it as (b-3)(b+10)

Answer 2

Answer:

In mathematics, factorization or factoring consists of writing a number or another mathematical object as a product of several factors, usually smaller or simpler objects of the same kind.

answer to your question ---

b²+7b-30

factors of 30 = 2, 15

multiplying factors ----- 10 × 3=30

adding factors ------- 10 -3 =17

so the factor of 'c' i.e 30

statisfy the rules of middle term factorization

b²+7b-30 =0

b²+10b-3b-30 = 0

b(b+10)-3(b+10) = 0

(b-3)(b+10) = 0

factors ----- (b-3)(b+10)

now we can get the value of b as 3 and -10

tips:

• know the process of middle term factorization
• do the calculation carefully
