Below is a picture of a handkerchiet. Do you know the shape ot this handkerchief? Mis a square.
How many sides are there in a square? Yes, a square has four
sides. So, this time we shall learn more about shapes.
What other shapes do you know aside from a square? They are
triangles, rectangles, trapezoid. mombus, parallelogram
pentagon, etc​

option (a)

step-by-step explanation:

step 1:   take 2 number whose product equal to 25..

and sum of those two number are -10

step: 2 for example here if we take 5,5 are the number,,

5*5=25

and

5+5=10

but we need -10

so if we take   -5,-5

so -5*-5=25

and -5+(-5)=-10

s0

come the equation

replace -10x by these number

like -5x -5x+25

take common

x(x-5)-5(x-5)=0

(x-5)(x-5)=0

isn't it a pentagon? sense [3 (triangle) + 4 (rectangle)] - 2 (triangle and rectangle connected) = 5 (pentagon)
