Question

find the product of (X+3) (X+7) ?​

Answer 1

Answer:

$(x + 3)(x + 7)$

${x}^{2} + 7x + 3x + 21$

${x}^{2} + 10x + 21$

Answer 2

Answer:

ok

Step-by-step explanation:

(x+3) ( x + 7)

= x(×+7) +3(×+7)

= ×^2+7×+3×+21

= ×^2+10×+21 = 0

this is quadratic equ

solve by factorisation method

= ×^2+10×+21 = 0

= ×^2 + 7×+3×+21 = 0

= ×(×+7) +3(×+7) = 0

= (×+7) (×+3) = 0

= ×+7 = 0. or. ×+3 = 0

= × = -7. or. × = -3
