Question

plzz answer we have to factorise it where the product is minus eight and the sum and difference is 7 no will be minus eight and 1 . We have to do it by splliting middle term ​

Answer 1

Answer:

(4m-1)(m+2)

Step-by-step explanation:

4m²+7m-2

= 4m²+8m-1m-2 -----> point number 1.

= 4m(m+2) -1 ( m+2 ) -------> point number 2.

= (4m-1)(m+2)

EXPLANATION :- in point 1 we have to find the product of the last two numbers which is 4 and (-2) = (-8)

and find the factors of -8 which when subtracted (as the number (-)8 is negative ) gives the result 7.

in point 2 we have to group the common factors and arrange then .

hope it helped.

thanks
