Answer:
In the first equation x=4 or x=-3
In the second equation x=-4 or x=3
Explanation:
The first equation x^2 − x − 12 can be factorized as follows:
x^2-4x+3x-12
x(x-4)+3(x-4)
x-4=0 or x+3=0
x=4 or x=-3
It is noteworthy that -x was rewritten as -4x+3x in order to solve the equation
The second equation x^2 + x − 12 can be factorized as below:
x^2+4x-3x-12
x(x+4)-3(x+4)
x+4=0 or x-3=0
x=-4 or x=3
It is noteworthy that +x was rewritten as 4x-3x in order to solve the equation
If a pea plant has two allele (yy) for seed colour, it follows that the genotype of the pea plant is homogenous for seed colour.
<h3>Homogenous allele</h3>
Gene inherited may be in two forms namely;
- Homogenous and Heterogenous
Heterozygous is characterized by having inherited different forms of a particular gene from each parent. A heterogenous genotype stands contrary to a homogenous genotype, where an individual inherits identical forms of a particular gene from each parent.

All of the aforementioned are implied by Viagra advertisements except that: women should be more se-xually assertive.
<h3>What is an advertisement?</h3>
An advertisement can be defined as consumer promotions programs that are designed and developed with the sole intention of making the various goods (products) or services which are being offered by a business firm to become known, popular and familiar to all of its customers and potential customers.
In this scenario, we can infer and logically that Viagra advertisements which depicts it as being an aphrodisiac and se-xual enhancer doesn't imply that women should be more se-xually assertive over their male counterparts (partners).
